Value Collection ZMSCE70021 Epdm O-ring Dash 021 Pack of 50

Product Description

The VALUE COLLECTION ZMSCE70021 is a Dash 021 EPDM O-ring with a round cross section, designed for sealing applications in fluid and hydraulic systems. It measures 0.9260 inches inside diameter, 1.0630 inches outside diameter, and 0.0625 inches thick. Made from Ethylene Propylene Diene Monomer (EPDM) with a hardness of 70 Shore A, this O-ring is rated for service from -65 degrees F to 300 degrees F. It is sold in a package quantity of 50. HVAC technicians, plumbers, and hydraulic service professionals install this type of seal in a wide range of pressurized fluid connections.

This O-ring is suited for use in hot water systems, steam service, and phosphate ester type hydraulic fluids. It also offers excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it appropriate for aerospace ground support and MRO applications in addition to standard plumbing and HVAC contexts. Residential and commercial mechanical systems that see elevated temperatures or steam exposure are common install environments. The round cross section fits standard Dash 021 O-ring grooves without modification.

Installation Notes

Installation of O-rings in pressurized fluid systems should be performed by a licensed plumber, HVAC technician, or qualified hydraulic service professional. Always depressurize the system and allow it to cool before removing any fittings or seals. Inspect the groove and mating surfaces for wear, scoring, or debris before seating the new O-ring. Lubricate the O-ring with a fluid compatible with EPDM material to ease installation and prevent tearing during assembly.
