Pump Parts,6pcs

Perfect fit for my Mommed S21 pumps! The quality is just like the original cups with the soft silicone, hard plastic, and all the pieces needed to work your wearable pump. I absolutely love my pumps, and the replacement parts are so affordable!

I bought these as a back-up set for my Mommed pump and they work great!!! The pieces fit together really nice, feel good quality, and you can't beat the price. Super happy and would definitely recommend.

Work very well. No issues

I was skeptical of buying aftermarket pump parts, but I shouldn’t have been! These fit my Momcozy S9s like a dream, and the suction is great. They are also compatible with inserts (not included), so don’t worry too much if your flange size isn’t listed—you can alter it.

I purchased two of these as they are sold individually. They looked just like my current tsrete cups so I threw away the packaging thinking they’d be the same. Sadly they don’t fit with tsrete and therefore does not give the same output. It’s not worth it. I usually can pump 4-5 ozs with this I barely got 1 total. Very frustrating. It seems it doesn’t give the correct seal therefore there isn’t good suction.

Bought these to replace the 27mm flanges the mommed S21 came with and it fits perfect. The quality feels the same as the ones that came with the pump as well.

I didn’t realize that this didn’t contain flanges for both sides! So just know that you’ll only get one if you order this/will need to buy two if you want to use your pump on both sides.

Great product that really works with the momcozy S12 (not S12pro).
