Value Collection ZMSCE70004 Epdm O-ring Dash 004 Pack 100

Product Description

The VALUE COLLECTION ZMSCE70004 is a Dash 004 EPDM O-ring designed for static and dynamic sealing applications in fluid handling systems. It features a round cross section with an inside diameter of 0.0781 inches, an outside diameter of 0.2030 inches, and a thickness of 0.0625 inches. Made from Ethylene Propylene Diene Monomer (EPDM) rubber with a Shore A hardness of 70, this O-ring is rated for service from -65 degrees F to 300 degrees F. It is sold in packs of 100. Licensed tradespeople in plumbing, HVAC, and industrial maintenance rely on this size for precision sealing in compact fittings and connections.

This O-ring is suited for use with hot water, steam, and phosphate ester type hydraulic fluids. It also delivers excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it appropriate for aerospace maintenance applications as well. The small Dash 004 profile fits compact threaded fittings, valves, and hydraulic components where a tight, reliable seal is required. Plumbers, HVAC technicians, and industrial maintenance professionals commonly stock this size for service and repair work.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or industrial maintenance professional. Depressurize and drain the system completely before removing or installing any O-ring. Inspect the seating groove for nicks, burrs, or debris before installation to avoid damage to the sealing surface. Do not use petroleum-based lubricants with EPDM O-rings, as they can cause the material to swell and degrade.
