Made from a sturdier silicone blend for improved performance and a reliable seal, helping maintain steady suction during pumping. Designed for parts that contact milk, it meets FDA and EU requirements for food contact.
Designed to work with Maymom backflow protector stems in long, medium, and short lengths, and with many popular pump backflow assemblies. Swapping worn membranes keeps your pump kit working without surprise drops in suction.
Available in different colors so you can tell new membranes from older ones at a glance, making routine replacements quicker. Keep a spare set ready so cleaning cycles do not interrupt pumping.
Choosing the right spare membranes keeps suction steady and cleaning simple.
- Check compatibility: Match the membrane to your backflow protector and the stem length used in your kit, for a snug fit and proper seal.
- Inspect wear signs: Replace membranes at the first sign of cracking, thinning, or loss of elasticity, which can reduce suction and allow backflow.
- Use color coding: Pick colored membranes or mark new sets so you can tell fresh parts from older ones at a glance.
- Keep spares handy: Store at least one spare set so you can swap parts during cleaning, especially if you pump daily.
- Follow cleaning rules: Clean membranes according to your pump and backflow protector instructions, and let parts air dry fully before reassembly.
Will these membranes work with my backflow protector?
These membranes are designed for Maymom backflow protector stems in long, medium, and short lengths and are compatible with many common pump backflow assemblies. If you are unsure, compare your current membrane shape and stem length to the product photos or contact our team for help.
How often should I replace the membranes?
Replace membranes as soon as you notice cracking, thinning, or reduced suction. Frequency depends on use, many pumping parents swap membranes anywhere from a few weeks to a few months.
How do I install and remove these membranes?
Press the membrane into the seat of your backflow protector until it sits flush, checking orientation so the rim seals evenly. Remove by gently pulling the edge, then clean and dry parts before putting in a fresh membrane.
Are these safe where breast milk touches them?
Yes, the membranes meet FDA and EU requirements for materials that contact food, which covers safe contact with expressed breast milk.
What are your shipping and return policies?
We ship from a US warehouse, and US orders over $100 qualify for free shipping. We offer 30-day returns, and our human customer support team is available if you need help with compatibility or returns.
