Jason ★★★★★ Sep 6, 2026

The silicone diaphragms feel sturdy and the whole assembly clicked together without any wrestling, which I appreciate at 6am. My output finally matches what I expected from a pump this size, and the extra valves mean I’m not scrambling for replacements mid-week.

The duckbill valves fit snugly and the silicone diaphragms feel sturdy, so swapping out the smaller size took me less than five minutes. Having two full assembly kits in the box is a nice bonus—I can keep one set clean while the other's in use.

I’ve been searching forever for a flange kit that actually fits my pump properly, and this one finally solves the sizing headache. The duckbill valves snap in securely and the whole assembly feels sturdier than the original parts I had. Glad I grabbed the two-pack so I always have a spare on hand.
