Description
Replacement silicone diaphragms for the Spectra Wearable Pump backflow protector. Sold in a pack of two.
The diaphragm is the soft circle inside the backflow protector that flexes with each pump cycle. It’s the part most customers wear out first — usually within four to six months of regular use. Replacing it restores the pump’s suction strength without needing to swap the whole protector.
These are specific to the Wearable Pump and are not interchangeable with the diaphragms used in the S1, S2, 9+ or M1 backflow protectors.
