Value Collection ZMSCE70202 Epdm O-ring Dash 202 100-pack

Product Description

The VALUE COLLECTION ZMSCE70202 is a Dash 202 EPDM O-ring with a round cross section, designed for use in fluid sealing applications across plumbing, HVAC, and hydraulic systems. It measures 0.25 inches inside diameter, 0.50 inches outside diameter, and 0.125 inches thick. Hardness is rated at 70 Shore A, placing it in the hard category. EPDM construction gives this O-ring excellent resistance to hot water, steam, phosphate ester hydraulic fluids, and ozone. Each package contains 100 O-rings, making it suitable for shop stock or service fleet replenishment. Licensed trade professionals and maintenance technicians are the primary installers.

This O-ring is appropriate for residential and commercial plumbing systems, HVAC equipment, and hydraulic assemblies where hot water, steam, or phosphate ester fluid contact is expected. It is also noted for resistance to Skydrol fluids used in commercial aircraft hydraulic systems, as well as compatibility with certain acids, alkalies, and ozone-rich environments. The Dash 202 designation is a standard AN/AS568 sizing reference, making cross-referencing straightforward across seal kits and parts catalogs. Packaged in quantities of 100, this listing supports bulk service needs.

Installation Notes

O-ring installation should be performed by a qualified plumber, HVAC technician, or hydraulic systems technician depending on the application. Always depressurize and drain the system before replacing any seal. Inspect the mating groove and sealing surfaces for damage, debris, or corrosion prior to installation. Avoid rolling or twisting the O-ring during seating to prevent premature failure.
