SAUNDERS A-015214425-1/2" PTFE/EPM DIAPHRAGM T268985

The Saunders A-015214425-1/2" (often labeled by the short-code DA015P2) is a high-purity Replacement Diaphragm for Saunders HC4 (Hygienic) and Type A weir-style valves. Saunders (a Crane CP&E brand) is the original inventor of the diaphragm valve, and this specific part is the "Gold Standard" for sterile processing. The 214/425 grade indicates a two-piece "Leaf Type" construction. It features a Grade 214 PTFE (Teflon) wetted face backed by a Grade 425 EPM (Ethylene Propylene) cushion. This combination provides the ultimate chemical inertness of PTFE with the flexibility and sealing memory of synthetic rubber.
