Value Collection ZMSCE70026 Epdm O-ring Dash 026 100-pack

Product Description

The VALUE COLLECTION ZMSCE70026 is a Dash 026 EPDM O-ring designed for static and dynamic sealing applications in fluid and steam systems. Constructed from Ethylene Propylene Diene Monomer (EPDM) rubber with a Shore A hardness of 70, this O-ring delivers reliable sealing performance across a wide service temperature range of -65 degrees F to 300 degrees F. The round cross-section profile measures 1.25 inches inside diameter, 1.375 inches outside diameter, and 0.0625 inches thick. Each package contains 100 O-rings. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install this type of seal in hot water, steam, and hydraulic fluid service lines.

This O-ring is suited for residential and commercial plumbing, HVAC, and hydraulic system maintenance. It performs in hot water and steam service, as well as phosphate ester type hydraulic fluid applications. The EPDM compound provides excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it a practical choice for aviation ground-support and MRO operations in addition to standard trade plumbing and HVAC installations. The 100-piece package quantity supports shop stock replenishment and fleet service programs.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified hydraulic system technicians. Always depressurize and drain the system before removing or installing O-rings. Inspect the mating groove for nicks, scoring, or corrosion before seating the new O-ring. Avoid twisting the O-ring during installation, and do not use petroleum-based lubricants with EPDM compound, as they will cause swelling and seal failure.
