If the suction on your Evenflo Advanced pump has started slipping, or you just want a backup set so you are never caught without clean parts, you are in the right place. Worn parts are the single most common reason a pump loses suction, and the good news is that Evenflo's parts are simple to identify, easy to swap, and often covered by insurance. Here is a clear guide to which Evenflo Advanced parts wear out, when to replace them, and how to get fresh ones without the hassle.
The Parts You Will Replace Most
The Evenflo Advanced uses a handful of components that come into contact with milk or create suction, and these are the ones to keep an eye on:
Membranes and valves: the small silicone pieces that create and hold suction, and the first to wear out. Diaphragms and diaphragm caps: part of the closed-system barrier that keeps milk out of the tubing and motor. Flanges (breast shields) and soft flange inserts: the funnels that fit against your breast, available in several sizes for a comfortable fit. Tubing and the tubing adapter: connect the pump to your kit. Collection bottles: where your milk is expressed and stored.
When to Replace Each Part
Knowing the general timelines helps you swap parts before performance drops, not after.
The silicone pieces wear fastest because they flex thousands of times per session. For the Evenflo Advanced, the manufacturer recommends replacing membranes, valves, and diaphragms roughly every 60 to 90 days if you pump daily. Beyond the calendar, watch for the physical signs: replace any part that shows tearing, cracking, stretching, cloudiness, or that no longer sits flat, and swap tubing that has trapped moisture or looks worn. Flanges and bottles are made of harder material and last longer, but should still be replaced if they crack, since crevices can harbor bacteria that cleaning cannot fully remove. Why it matters: worn membranes and valves are the number one reason pumps lose suction, and weaker suction means longer sessions and, over time, can affect your supply. Replacing small parts on schedule keeps your Evenflo working like new. If your suction has dropped, it is also worth double-checking your flange fit with the Storkpump flange sizing guide, since fit and worn parts are the two most common culprits.
What Comes in the Evenflo Replacement Parts Kit
Rather than tracking down pieces one at a time, Evenflo offers a complete replacement parts kit designed for the Advanced Double Electric pump.
The Evenflo replacement parts kit typically includes two 30.5 mm flange kits, soft flange inserts in 28.0 mm and 24.5 mm to help you fine-tune your fit, a set of tubing, a tubing adapter, two diaphragms, two diaphragm caps, two membranes, and two valves. In other words, it refreshes all the parts that wear out and gives you multiple flange sizes in one go. The parts are made of BPA-free, food-grade material. A nice bonus: keeping a spare kit at work, in the car, or in your bag means you always have a clean set ready, so a broken part or a rushed morning never derails a session.

How to Get Evenflo Parts Through Insurance
Here is the part many parents do not realize: your insurance may cover replacement parts, not just the pump itself.
Under the Affordable Care Act, most plans cover breastfeeding equipment, and many also cover replacement parts, though how often varies by plan (some allow parts monthly, others quarterly or annually). To get Evenflo parts through insurance, you order through an accredited durable medical equipment (DME) supplier, which is required for insurance-covered supplies. Storkpump can verify your specific benefits, confirm how often you qualify, and ship the right Evenflo parts to your door, often at little to no out-of-pocket cost. Because parts are not universal, always match them to your exact pump (the Evenflo Advanced Double Electric), which the kit above is designed for. For more on how coverage works, see our FAQ page.
Frequently Asked Questions About Evenflo Breast Pump Parts
How often should I replace Evenflo membranes and valves?
Evenflo recommends replacing membranes, valves, and diaphragms roughly every 60 to 90 days with daily pumping. Beyond the timeline, replace any piece that shows tearing, cracking, stretching, or a decline in suction. These small silicone parts are the most common cause of lost suction, so they are the first thing to check.
What parts come in the Evenflo replacement kit?
The Evenflo replacement parts kit for the Advanced Double Electric pump typically includes 30.5 mm flange kits, soft flange inserts in 28.0 mm and 24.5 mm, tubing, a tubing adapter, diaphragms, diaphragm caps, membranes, and valves. It refreshes all the parts that wear out and gives you multiple flange sizes in one kit.
Are Evenflo replacement parts covered by insurance?
Often yes. Many insurance plans cover breast pump replacement parts, though how often varies by plan. You will need to order through an accredited DME supplier. Storkpump can verify your benefits, confirm your replacement frequency, and ship the right parts to you, often at little to no cost.
Will any breast pump parts work with my Evenflo?
You should use parts made for your specific pump, the Evenflo Advanced Double Electric, since components are not interchangeable between brands and models. Evenflo's own Advanced pumps share interchangeable parts across the line, but mixing in other brands' parts can affect suction and fit.
How do I know my suction problem is a part and not the pump?
Start with the cheapest, most likely culprits: the membranes and valves, which wear out fastest. Also confirm everything is assembled correctly and your flange fits well. If suction is still weak after replacing the silicone parts and checking assembly and fit, the motor may be the issue, and you can reach out about next steps.
