.275" C/S (1/4" NOMINAL) (6.99 MM)

Item 0283H275 is a FKM Viton 90A O-Ring Cord built for custom O-ring fabrication, spliced seals, field repairs and nonstandard groove diameters. The item is specified by 0.275 inch (6.99 mm) cross section, with 1/4 inch nominal CS for cross-reference against common gland and replacement dimensions. The FKM/Viton fluoroelastomer compound is selected for 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 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. Key selection details include material, hardness, product type, cross-section, inside diameter, outside diameter and application. These specification details help customers and resellers compare the part by performance requirements rather than brand name alone.
