## Description

desertcart.com : Maymom Silicone Membrane; Designed for Spectra S1 S2, 9 Plus Backflow Protector and Maymom Backflow Protectors, Long, Short and Medium; Not Original Spectra S2 Accessories or Pump Part : Baby

Review: Works just as well as brand name - Much cheaper than the Spectra name brand parts and work just as well with my Spectra S1 pump. The cute color is an added bonus.
Review: Great Affordable Alternative to Brand Name Parts - These replacement duckbill valves are great. They were delivered quickly and are a very cost-effective option compared to the brand name parts. They function just the same as far as I can tell in terms of output, so I have not noticed any difference at all when using them. I also really like that they come in different colors. It makes it easy to keep track of which parts have been replaced and which ones still need to be, which is super helpful when rotating pieces. Overall, a great value and I would definitely purchase again.

## Questions & Answers

**Q: Are these the same membranes that are sold in a two-pack (asin b07hk8sygl)?**
A: YES.  it is just comes in 4 pc, not 2.  It is a saving as it is the same FBA fee (which is a lot) not matter it is 2 pc or 4 pc.

**Q: Are these BPA free?**
A: It does not specify. However, this part is not in contact with the milk so may not be relevant if has BPA or not.

**Q: It's pictured with 4 membranes, but I don't see where it specifies exactly how many are actually included... is it really 4?**
A: HI, you will get what you see on the main photo - that is 4 membranes.

**Q: Is this compatible with the medela pump in style?**
A: No

### ⭐⭐⭐⭐⭐ Works well with Spectra S1
*by A***R on July 1, 2025*

When the membrane diaphragms that came with my Spectra S1 pump just weren’t adequately doing the job anymore, I found these! After reading through the reviews, I decided these would best fit my needs. I like that they feel a little thicker than the Spectra ones, so I’m hoping they may last longer. I also like that they have different colors! I went with the pink to match my duckbills from Legendairy. I’m very pleased with these and will order again in the future!
