.139" C/S 70 DUROMETER BLUE FKM

Use item 0283MD139 when a FKM Viton 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 FKM/Viton fluoroelastomer construction supports high-temperature service, fuels, lubricants and many chemical sealing environments. It is with a listed temperature range of -15°F (-26°C) to 400°F (204°C), which can help narrow material selection for heat, cold or process exposure. The blue 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. Its metal-detectable formulation supports detectable sealing applications where lost-part risk management is part of the specification. 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.
