Wearable Breast Pump Accessories Milk Collector Cup Replacement Parts Flange 24mm Compatible with Mommed TSRETE Missaa Mumgaroo S21/S19/S18 Pump, Bonus 1pcs Duckbill Valve&Silicone Diaphragm

They fit well on my eufy pump.

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

These are great, they worked well with my imani wearable pumps. Also so helpful that I can use these instead of entirely buying a new pump or parts that are super expensive.

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.

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.

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.

Worked great until they started leaking not a big fan didn’t have very long before started leaking

Worked out great fit my wearable pump snuggley
