4 MM (.157") BROWN O-RING CORD

This FKM Viton 75A O-Ring Cord, item 0M283VB4, is designed for buyers who need a clear specification match for custom O-ring fabrication, spliced seals, field repairs and nonstandard groove diameters. The item is specified by 0.157 inch (4 mm) cross section, with 4 inch nominal CS for cross-reference against common gland and replacement dimensions. Its FKM/Viton fluoroelastomer material provides 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 brown 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. Common purchasing identifiers for this product include the material name, O-ring type, dimensional size, hardness and intended sealing application. Those attributes make the item easier to compare for maintenance, OEM production, MRO replacement and reseller catalog use.
