Value Collection ZMSCE70920 Epdm O-ring Dash 920 Pack of 60

Product Description

The VALUE COLLECTION ZMSCE70920 is a Dash 920 EPDM O-ring designed for sealing applications in hydraulic, plumbing, and steam systems. It measures 1.475 inches inside diameter, 1.711 inches outside diameter, and 0.118 inches thick with a round cross section. The ethylene propylene diene monomer construction provides a Shore A hardness rating of 70, placing it in the hard range for reliable compression sealing. This O-ring functions as an O-ring boss gasket for straight-thread tube fittings and is suited for installation by licensed plumbers, HVAC technicians, and fluid systems technicians working with hot water, steam, or phosphate ester hydraulic fluids.

This O-ring is appropriate for residential and commercial applications involving hot water systems, steam lines, and phosphate ester type hydraulic fluid circuits. The EPDM material also offers excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it relevant for aviation ground support and maintenance environments. Each package contains 60 O-rings, supporting both single-repair and bulk service kit needs. The operating temperature range of -65 degrees F to 300 degrees F covers most hydronic, steam, and industrial hydraulic service conditions.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or hydraulic systems technician. Shut off and depressurize the system completely before removing or replacing any O-ring. Inspect the mating boss seat surface for scoring or debris before seating the new ring. Do not use petroleum-based lubricants with EPDM O-rings; use a compatible silicone or water-based lubricant only.
