Spectra Diaphragm Loose (single)

Spectra’s silicone diaphragm fits the three piece connector. All silicone parts will thin and loose elasticity due to normal wear and tear. Replace your diaphragm if you notice a visible tear, or if your pump seems to be losing suction (keep in mind that the Silicone valves is also a likely culprit should this occur and should ideally be replaced every 3 months).
