Value Collection ZMSCE70041 Epdm O-ring Dash 041 Pack of 20

Product Description

The VALUE COLLECTION ZMSCE70041 is an EPDM O-ring with a round cross section, sized at 3 inches inside diameter, 3-1/8 inches outside diameter, and 1/16 inches thick. It carries a Dash 041 designation and a Shore A hardness rating of 70, placing it in the hard category. EPDM compound provides excellent resistance to hot water, steam, and phosphate ester hydraulic fluids, and is also noted for resistance to Skydrol fluids used in commercial aircraft hydraulic systems. Licensed plumbers, HVAC technicians, millwrights, and hydraulic system technicians install this type of seal in fluid-handling assemblies operating across a wide service temperature range.

This O-ring is suited for use in residential and commercial plumbing systems, hydronic heating systems, steam distribution lines, and hydraulic equipment where phosphate ester fluids are present. The EPDM material makes it a practical choice for hot water and steam sealing applications. Each package contains 20 O-rings with a minimum order quantity of 1 package, making it appropriate for service shops stocking standard seal sizes or technicians completing multiple repairs.

Installation Notes

Shut down and depressurize the system and allow it to cool before replacing any O-ring seal. Inspect the mating groove for wear, scoring, or debris before installing the new seal. Lubricate the O-ring with a fluid compatible with EPDM and the system medium before seating — do not use petroleum-based lubricants with EPDM seals. Verify the groove dimensions match the Dash 041 specification before installation to prevent extrusion or insufficient sealing force.
