Customer Reviews (5.0 / 5 · 5 reviews)

Alexander ★★★★★

I set a reminder to swap these out every 90 days like the instructions say, and the new valves felt noticeably snugger than the worn ones I'd been using. Glad I didn't wait until something started hurting or leaking.

Matthew ★★★★★

The flanges and valves fit my pump exactly and swapping everything in took under five minutes. I replaced everything at the three-month mark as suggested, and the suction feels noticeably more comfortable on my first session after the change.

Scarlett ★★★★★

I was overdue for my 90-day swap and these replacement parts arrived just in time. The duckbills feel sturdier than the originals and the flanges snap on with a satisfying click, no wrestling required. Definitely keeping a spare set on hand now that I know the difference fresh parts make.
