Value Collection ZMSCE70032 Epdm O-ring Dash 032 Pack 100

Product Description

The VALUE COLLECTION ZMSCE70032 is an EPDM (Ethylene Propylene Diene Monomer) O-ring with a round cross section, designed for static and dynamic sealing applications in fluid and thermal systems. It measures 1.875 inches inside diameter, 2 inches outside diameter, and 0.0625 inches thick, conforming to Dash 032 sizing. With a 70-durometer hardness rating, the ring maintains a firm, reliable seal under mechanical compression. EPDM compound provides excellent resistance to hot water, steam, and phosphate ester hydraulic fluids, making it a practical choice for plumbing, HVAC, and industrial service technicians working on high-temperature or fluid-transfer systems.

This O-ring is suited for residential and commercial plumbing, HVAC hydronic systems, steam service connections, and hydraulic fluid applications using phosphate ester-type fluids. It is also noted for excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems. The part is sold in a package quantity of 100, making it appropriate for shop stock, service vans, or maintenance programs where this dash size is frequently used. The minimum order quantity is 1 package.

Installation Notes

O-rings of this type are installed by licensed plumbers, HVAC technicians, and industrial mechanics depending on the application. Always depressurize and drain the system before replacing any sealing component. Inspect the mating groove for damage, debris, or corrosion before seating the new ring. Avoid twisting or rolling the O-ring during installation, and do not use petroleum-based lubricants with EPDM compound, as they can cause swelling and seal failure.
