Living with an insulin pump means building a system around it. The pump itself is just the starting point. What makes day-to-day management smoother, safer, and more comfortable is everything that surrounds it: the infusion sets, the cases, the adhesives, the sleep strategies, and the travel kit you assemble over time. This guide covers all of it, organized by what you actually need to know.

What Are Insulin Pump Accessories? (And Why They Matter More Than You Think)
Insulin pump accessories fall into three distinct tiers, and understanding the difference helps you spend smarter and manage better.
The first tier covers medical necessities — infusion sets, reservoirs or cartridges, and insertion devices. These are clinical supplies you cannot skip. The second tier includes comfort and protection items — cases, holsters, screen protectors, and adhesive overlays that protect your equipment and your skin. The third tier is lifestyle optimization gear — the sport bands, travel cooling cases, pump-pocketed clothing, and sleep solutions that make wearing a pump feel less like a medical exercise and more like a daily routine.
Most resources online cover only one of these tiers. This guide covers all three, because how well you manage your accessories directly affects how well your pump works.
The Medical Must-Haves: Infusion Sets, Reservoirs, and Insertion Devices
Every pump user needs a steady supply of medical consumables, and understanding what you're ordering matters as much as ordering it consistently.
Types of Infusion Sets
Infusion sets connect your pump to your body via a small cannula (a soft, flexible tube) or steel needle inserted just below the skin. They come in two primary configurations.
Angled sets insert the cannula at a 30–45 degree angle and work well for people with leaner body composition or those who find 90-degree insertion uncomfortable. The angle distributes the cannula along a longer subcutaneous path, which some users find more stable.
90-degree sets insert straight down and are often preferred for users with more subcutaneous tissue, as they sit more securely. They're the more common default for new pumpers.
Beyond angle, the material matters. Soft cannula sets use Teflon-coated flexible tubing that bends slightly with movement, making them well-suited for active users. Steel needle sets remain rigid and are often recommended for users who experience frequent cannula kinking, a documented issue with soft sets in areas of dense tissue or high movement.
Tubing length is another variable. Short tubing (18–23 inches) works for clip-on wearing near the infusion site. Longer tubing (32–43 inches) suits users who prefer placing the pump in a pocket, bag, or thigh band farther from the site.
Research published in the Journal of Diabetes Science and Technology found that infusion set failure — defined as unexplained hyperglycemia from site or cannula issues — remains one of the most common causes of glucose disruption in automated insulin delivery systems. Choosing the right set for your body type and activity level reduces that risk.
Extended-Wear Infusion Sets
Standard infusion sets are changed every 2–3 days. Extended-wear options have expanded that window.
The Medtronic Extended Set is approved for up to 7 days of wear, designed specifically for the MiniMed 780G system. The Tandem SteadiSet, which received FDA clearance in 2025, is similarly designed for 7-day wear and is compatible with the Tandem t:slim X2 and Tandem Mobi systems.
Extended-wear sets require more deliberate site rotation planning, since a single site absorbs insulin for a longer period. Users also typically need to use a longer cannula format to maintain absorption as the site matures over the week. A diabetes care and education specialist (DCES) can advise on whether extended-wear sets are appropriate for an individual's glucose management patterns.
Reservoirs and Cartridges
Reservoirs are the internal insulin containers used in tubed pumps like the Tandem t:slim X2 and Medtronic 780G. Cartridges are the pre-filled or fillable pods used in tubeless systems like the Omnipod 5.
Reservoirs in tubed pumps are typically changed every 2–3 days, aligning with infusion set changes. Most pumps require pump-specific reservoirs — for instance, Tandem reservoirs are not interchangeable with Medtronic reservoirs. Always verify compatibility before ordering in bulk.
The iLet Bionic Pancreas system, developed by Beta Bionics, uses a different cartridge format entirely and requires supplies ordered through Beta Bionics or authorized distributors.
Protecting Your Pump: Cases, Clips, Holsters, and Covers
A pump case does more than prevent scratches. It absorbs impact, keeps moisture out, and extends the life of a device that typically costs thousands of dollars before insurance.
Hard Cases vs. Silicone Covers
Hard cases offer the best drop protection. They're typically made from polycarbonate or ABS plastic and snap around the pump body. The tradeoff is added bulk and slightly reduced access to buttons and ports.
Silicone covers (sometimes called "skins") add grip and light scratch protection without bulk. They're easier to put on and remove and allow full access to touchscreens and charging ports. For everyday, lower-risk environments, a silicone skin is usually sufficient.
Pump-specific cases are generally better than universal options. Brands like Nite Ize, Myabetic, and several pump manufacturers themselves offer model-matched cases. For the Tandem t:slim X2, the slim profile makes it compatible with some phone case accessories in addition to dedicated options. For the Medtronic 780G, the pump's larger body requires 780G-specific cases.
Belt Clips and Holsters
For users who prefer wearing the pump on the waistband, belt clips and holsters are the default choice.
The Omnipod 5 is tubeless, so it doesn't require a holster for the pod itself — but the Omnipod PDM (personal diabetes manager) controller does benefit from a clip or small pouch. For tubed systems, a holster keeps the pump accessible and reduces tubing tension.
Brand-specific holsters are available from each pump manufacturer. Third-party options on Amazon and diabetes supply retailers often offer leather, nylon, or canvas styles with added features like multiple zipper compartments for wipes, backup cannulas, and glucose tabs. On more active days, a rotating belt clip that pivots with movement is preferable to a fixed-position clip.
Screen Protectors and Port Plugs
These are the most overlooked accessories on most lists, and the most cost-effective.
Screen protectors prevent touchscreen scratches that, over time, reduce readability. For the t:slim X2, which has a full-color touchscreen display, a tempered glass protector is worth the few dollars it costs.
Port plugs cover the charging and supply ports on pumps when not in use. They prevent debris from compromising port connections, which is particularly relevant for users in dusty, outdoor, or beach environments.
How to Wear Your Pump: Belts, Bands, Pockets, and Clothing Solutions
Wearability is one of the biggest quality-of-life concerns for new pumpers — and one of the least-covered topics in most accessory guides.
Waist Belts and SPIbelts
The SPIbelt (Small Personal Item Belt) is a thin elastic belt with a small zippered pouch that expands to hold a pump and a few small supplies. It sits flat against the abdomen under clothing and is a favorite for exercise and running because it doesn't bounce or shift.
For users managing diabetes actively, comfort during physical activity is a real concern, and a well-fitted waist belt is often the simplest answer. Sizing matters: the belt should be snug enough not to slip but not so tight that it compresses the pump or creates skin irritation under the pouch.
Other waist band options include wider bands made of moisture-wicking fabric, which are more comfortable in warmer climates or during high-output exercise. The Flip Belt is a popular alternative that doesn't require a zipper and distributes weight more evenly.
Thigh and Arm Bands
Thigh bands are particularly useful for users wearing dresses, skirts, or formal attire where waist placement isn't practical. They strap around the thigh with elastic and velcro and hold the pump securely against the leg. Bands4Life and In A Snap are two well-reviewed options.
Arm bands work similarly but position the pump on the upper arm. They're less common for heavier pump models but suit the smaller tubeless PDMs well.
Pump-Pocketed Clothing
Several apparel brands now produce clothing with built-in pockets designed specifically for insulin pumps. Underskin and Sugar Medical offer tanks, underwear, and shorts with discreet pump compartments. These are particularly popular among women, who face a specific challenge: most standard clothing is not designed with any meaningful pocket storage, let alone secure medical device pockets.
Sleeping with Your Pump
For many users, nighttime is the most awkward pump management challenge. A few solutions work well in practice.
Clip-on pajama pockets — small fabric pouches that attach to waistbands or necklines — keep the pump accessible without requiring you to loop tubing through layers of bedding. Nighttime-specific waist bands made from softer, thinner material are comfortable for sleeping and reduce the risk of pressure points.
Tubing management during sleep is mostly about keeping the tube clear of the site and not looping it around a limb that you might roll onto. Many users simply tuck the pump under the pillow or into a loose pajama pocket, which works fine for most sleep positions. For users who move a great deal during sleep, a longer tubing length — 43 inches — gives more slack without pulling on the infusion site.
Adhesives, Skin Prep, and Tape: Keeping Your Infusion Set in Place
Site adhesion is where many pump users lose the most time and glucose control. A set that lifts or peels early causes unpredictable insulin delivery — and often requires an unplanned site change.
Research published in the Journal of Diabetes Science and Technology reviewed adverse skin reactions associated with insulin pump therapy and found that adhesive-related issues — including contact dermatitis, folliculitis, and lipohypertrophy — are among the most frequently reported complications. Proper skin prep and the right adhesive products reduce these significantly.
Skin-Prep Wipes and Adhesive Primers
Skin Tac is a widely used adhesive primer that creates a tacky barrier on the skin before infusion set placement. It significantly improves adhesion for users with oily skin, hyperhidrosis (excessive sweating), or those living in humid climates.
Smith & Nephew Skin Prep wipes are alcohol-free and provide a protective film that helps adhesives bond more effectively without irritating sensitive skin. These are particularly useful for children or adults with eczema-prone skin.
Avoid placing infusion sets on freshly moisturized skin. Lotions and oils are adhesive's worst enemy. Allowing the skin to dry fully after cleaning — typically 30–60 seconds — before insertion improves bond strength.
Overtape and Adhesive Patches
Overtape is a thin, flexible medical tape applied over the existing infusion set patch to reinforce its edges and prevent peeling. Popular options include Skin Grip, Kinesiology tape (cut to size around the cannula site), and Pump Peelz, which also offer decorative patterns.
The key with overtape is cutting a donut or frame shape that covers the edges of the infusion patch without covering the cannula insertion point. Covering the cannula risks kinking or dislodging the set when the tape is later removed.
For users who experience consistent lifting at a particular site, a hydrocolloid patch (like a thin medical bandage) placed around the infusion set as a foundation layer can dramatically improve adhesion before the infusion patch goes on.
Adhesive Removers
Removing infusion sets and CGM sensors without causing skin trauma requires the right product. Uni-Solve and Nair Medical adhesive remover sprays or wipes break down the adhesive without requiring mechanical peeling, which causes micro-tears in the skin.
Using an adhesive remover at every set change — rather than pulling off patches dry — reduces cumulative skin damage and helps prevent the scarring and site sensitivity that develops over years of pump use.
Accessories for Active Lifestyles — Sports, Swimming, and Travel
Physical activity and travel introduce specific challenges for pump users that most accessory guides don't fully address.
Waterproof Cases for Swimming
Most current insulin pumps carry some level of water resistance. The Tandem t:slim X2 is rated IPX7, meaning it can withstand submersion in up to 1 meter of water for 30 minutes. The Medtronic 780G carries a similar rating. The Omnipod 5 pod is waterproof to 25 feet for 60 minutes.
However, "water resistant" and "swim-proof" are not identical, and extended pool or ocean use pushes those limits. External waterproof cases provide additional protection.
The Aquapac Insulin Pump Case is the most referenced option for swimming. It uses a roll-seal closure system and is rated for full submersion. It's compatible with tubed pumps and allows bolus buttons to be pressed through the soft case material. For open-water swimming or prolonged aquatic activity, this kind of external case adds meaningful protection beyond the pump's built-in rating.
For users who simply want protection from splashing, rain, or poolside humidity, a simpler waterproof pouch or Ziploc-style case may be sufficient and far less expensive.
Exercise Bands and Sport Holsters
During running, cycling, and high-movement sports, tubing management is the main variable. A pump holster worn on the waistband can shift during movement and create tubing tension at the infusion site.
A few strategies work well for athletes. First, switching to shorter tubing on active days reduces the slack that can catch on clothing or equipment. Second, securing the tubing with a small medical tape loop (just enough to hold the tube against the skin) at one point between the pump and site prevents tubing from swinging freely. Third, sport-specific holsters with tighter, more compressed fits reduce bounce and shift.
For contact sports, some users temporarily disconnect from their pump at the infusion set connection point, which most modern sets support. A diabetes care team can advise on appropriate insulin management strategies during disconnection periods.
Travel Essentials
Traveling with a pump requires a few additions to the standard accessory kit.
Insulin cooling cases — such as those from Frio or MedAngel — use evaporative cooling or phase-change material to keep insulin stable without refrigeration. This matters for travel to warm destinations or for users spending extended time outdoors.
At airport security, TSA allows insulin pumps to remain on during screening. You can request a manual pat-down instead of walking through the full-body scanner, as some pump manufacturers recommend avoiding prolonged electromagnetic exposure from certain scanner types. Carrying a brief letter from your prescribing physician and a copy of your pump's documentation makes the process faster.
A travel backup kit should include at minimum: two extra infusion sets, one extra reservoir, skin prep wipes, overtape, adhesive remover, and enough insulin for 48 hours beyond your planned trip length.
Insulin Pump Accessories for Kids and Teens
Managing insulin pump accessories for a child involves a different set of priorities — security, comfort, durability, and making the pump feel like something other than medical equipment.
Fun Cases and Skins
Customizable pump skins and decorative cases help younger children feel less self-conscious about their devices. Several brands offer patterned vinyl skins for major pump models, including dinosaur prints, galaxy themes, and sports designs. Pump Peelz is particularly popular in the pediatric diabetes community for its variety and skin-safe adhesive.
For smaller children, a soft silicone cover in a bright color can make the pump easier to identify and harder to lose — a real concern with young, active kids.
School-Safe Wearing Solutions
In school settings, the pump needs to be secure, accessible for bolusing, and ideally not disruptive to the child's clothing or movement. Waist bands that sit under the uniform, or thigh bands that don't show under trousers or skirts, are popular choices for school days.
Some parents opt for small pouches worn on a lanyard or clipped to the inside of a waistband, allowing a teacher or nurse to access the pump quickly if needed. For PE class specifically, a tighter sport band holds the pump more securely during movement.
Growing Pains: How Needs Shift Over Time
A toddler's accessory needs are almost entirely about keeping the pump attached and protected. Parents often use one-piece rompers or specially designed onesies with pump pouches to prevent small children from pulling at infusion sites or the pump itself.
By middle school, kids typically want more autonomy over how they wear and manage their pump. Arm bands, thigh bands, and the same sport solutions adults use become more relevant. Many teens begin making their own accessory choices — a meaningful step in taking ownership of their diabetes management.
What Does Insurance Cover? HSA and FSA Eligibility for Pump Accessories
Understanding what your plan covers — and what you can pay for tax-free — can meaningfully reduce your out-of-pocket accessory costs.
Medical Supplies: Infusion Sets and Reservoirs
Infusion sets, reservoirs, cartridges, and insertion devices are classified as durable medical equipment (DME) under most US health insurance plans. Coverage requires a valid prescription and is typically subject to your deductible and DME cost-sharing percentage.
The American Diabetes Association recommends reviewing your plan's DME benefit tier and whether your preferred supplies require prior authorization, as this varies by insurer and plan type. Mail-order supply programs often reduce per-unit cost compared to retail pharmacy dispensing.
Comfort Accessories: Cases, Belts, and Bands
The IRS defines FSA/HSA-eligible expenses as those "primarily for the prevention or treatment of a physical or mental illness, or for the purpose of affecting a structure or function of the body." Pump cases, holsters, and waist bands occupy a grey area.
As a general rule, if an accessory is prescribed by a physician as medically necessary (for example, a waterproof case prescribed for a patient who swims as part of a rehabilitation program), it may qualify. Without a letter of medical necessity, comfort accessories are typically not FSA/HSA eligible.
Skin prep products (Skin Tac, Uni-Solve) and medical overtape generally do qualify as FSA/HSA eligible since they directly support a prescribed medical device.
Using FSA/HSA Funds Effectively
For 2025, the IRS set the FSA contribution limit at $3,300 for employer-sponsored plans. HSA limits for 2025 are $4,300 for individuals and $8,550 for families with a high-deductible health plan.
Timing bulk infusion set and reservoir orders to fall within a single benefit year maximizes what you can cover tax-free. If you know you have FSA funds that won't roll over (most FSA plans have a "use it or lose it" structure), stocking up on skin prep wipes, adhesive removers, and overtape before the year-end deadline is a practical way to extend your supplies budget.
Building Your Starter Kit — A Checklist for New Pumpers
New pumpers are often overwhelmed by supply options. Here is a practical baseline.
Medical necessities (non-negotiable):
- Infusion sets (appropriate angle, cannula material, and tubing length for your body and lifestyle)
- Reservoirs or cartridges (pump-specific; buy at least a 90-day supply)
- Insertion device (included with most pump starter kits)
- Extra infusion sets for unplanned changes (2–3 extra per week)
Skin and adhesion (strongly recommended):
- Skin prep wipes or Skin Tac adhesive primer
- Overtape or adhesive patches (Skin Grip, Pump Peelz, or kinesiology tape)
- Adhesive remover wipes or spray
Protection (buy early, buy once):
- A pump case or silicone cover matched to your pump model
- Screen protector for touchscreen pumps
- Port plugs for your pump's charging and supply ports
Wearability (add based on lifestyle):
- Waist belt or SPIbelt for everyday carry or exercise
- Thigh or arm band for formal wear or dresses
- Nighttime waist band or clip-on pajama pocket
For travel:
- Insulin cooling case (Frio or equivalent)
- A documented backup supply kit for 48 hours beyond your trip

Frequently Asked Questions
What accessories do I need for an insulin pump?
Every pump user needs infusion sets, reservoirs or cartridges, and skin prep supplies as a baseline. Beyond those medical necessities, a protective case, an overtape or adhesive patch, and a wearability solution — such as a waist belt or thigh band — cover most daily situations. Active users and travelers will want waterproof protection and a cooling case for insulin. New pumpers should start with the basics and add lifestyle accessories once they understand their daily wear patterns.
What is the best case for an insulin pump?
The best pump case depends on your pump model and primary concern. For drop protection, a hard polycarbonate case made specifically for your pump (Tandem t:slim X2, Medtronic 780G, or Omnipod PDM) is the strongest option. For everyday use with minimal bulk, a pump-matched silicone skin provides grip and scratch protection without adding size. For swimming, the Aquapac Insulin Pump Case is the most widely used external waterproof option.
Where are the best sites to insert an insulin pump infusion set?
The abdomen is the most commonly used and generally most predictable infusion site for most people. The upper buttocks, thighs, and upper arms are also viable sites. Site rotation — moving the infusion site at least 1–2 inches from the previous location with each change — prevents lipohypertrophy (hardened scar tissue) and maintains consistent insulin absorption. A diabetes care specialist can help map a rotation schedule suited to your body.
How do I keep my insulin pump waterproof while swimming?
Most current pumps are water-resistant to a depth of 1 meter for 30 minutes, but that rating doesn't cover prolonged swimming. For pool or open-water swimming, an external waterproof case such as the Aquapac Insulin Pump Case provides full submersion protection. The Omnipod 5 pod is tubeless and rated waterproof to 25 feet for 60 minutes, requiring no additional protection. Always check your specific pump model's IPX rating and the manufacturer's current guidance before swimming.
How often should I rotate my insulin pump infusion sites?
Most clinical guidelines recommend rotating infusion sites with every set change, which occurs every 2–3 days for standard sets or every 7 days for extended-wear sets. The American Diabetes Association advises avoiding previously scarred or hardened tissue, as lipohypertrophy at overused sites absorbs insulin inconsistently and can cause unexplained glucose variability. A structured rotation map — dividing the abdomen into quadrants and moving clockwise — helps maintain even distribution across sites.
Can I use HSA or FSA funds for insulin pump accessories?
Infusion sets, reservoirs, and cartridges are DME-classified and generally HSA/FSA eligible with a prescription. Skin prep products and medical-grade overtape also typically qualify. Comfort accessories like cases, belts, and holsters are a grey area — they may qualify with a physician's letter of medical necessity, but are not automatically eligible. Check with your plan administrator or refer to IRS Publication 502 for the current eligible expense list.
