.139" C/S (1/8" NOMINAL) (3.53 MM) epdm

Use item 0282139 when an EPDM 70A O-Ring Cord is required for custom O-ring fabrication, spliced seals, field repairs and nonstandard groove diameters. The item is specified by 0.139 inch (3.53 mm) cross section, with 1/8 inch nominal CS for cross-reference against common gland and replacement dimensions. The EPDM (EPR) construction supports water, steam, weathering and outdoor sealing applications where petroleum oil exposure is not the primary requirement. The black color and round profile provide a practical visual identifier during receiving, stocking and installation. As O-ring cord, it gives fabricators flexibility to cut and splice seals when a molded size is not practical or available. It is sold as cord stock, making it useful for fabricating custom O-rings or replacement seals in nonstandard diameters. Important product identifiers include O-rings, replacement seals, fluid sealing, material compatibility and dimensional fit. It supports customer comparison, distributor cataloging and specification-based selection without relying on pricing, availability or shipping claims. Engineers, maintenance teams and purchasing groups can use the listed dimensions to verify fit before selecting the seal for a groove or assembly.
