Value Collection ZMSCE70317 Epdm O-ring Dash 317 70 Duro

Product Description

The VALUE COLLECTION ZMSCE70317 is a Dash 317 EPDM O-ring with a round cross section, designed for static and dynamic sealing applications where exposure to hot water, steam, or phosphate ester hydraulic fluids is expected. The ring measures 0.912 inches inside diameter, 1.313 inches outside diameter, and 0.1875 inches thick, with a Shore A hardness of 70. EPDM compound delivers reliable performance across a wide service temperature range, making it a practical choice for plumbing, HVAC hydronic systems, and industrial fluid handling. Licensed tradespeople and maintenance technicians are the primary installers.

This O-ring is suited for residential and commercial applications involving hot water lines, steam systems, and phosphate ester type hydraulic circuits. The EPDM material also offers excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, expanding its utility to aviation maintenance environments. Typical use cases include valve stem seals, flange face seals, and pipe union connections where thermal cycling and fluid compatibility are primary concerns. Sold in packages of 60 units, this SKU is well suited for shop stock and service van inventory.

Compatibility

Compatible materials include hot water, steam, and phosphate ester hydraulic fluids. Designed as a standard Dash 317 O-ring replacement for any application requiring an EPDM seal of this cross section and diameter.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC hydronic technicians, or maintenance mechanics. Shut off fluid supply and relieve system pressure before replacing any O-ring seal. Inspect the groove for scoring or contamination that could compromise the new seal. Avoid using petroleum-based lubricants with EPDM O-rings, as they can cause swelling and premature failure.
