Pump Valves - 4 Pack for Signature Pro and Smartpump

Wasn't sure these would fit right but they snapped onto the flange body just like the originals. Suction feels strong again and I'm getting the same output as when the pump was new. Four in a pack means I've got backups on hand for the next time one wears out.

My suction went back to normal the day I swapped in a fresh valve, which saved me from buying a whole new pump. They clip onto the flange body easily and the diaphragm seats fine on top. Four in a pack means I've got spares for when these wear out.

The seal on these fits way tighter than the old ones I had, so suction feels consistent every single pump session now. I swapped all four in about two minutes and haven’t had a single drop of lost pressure since.
