1/2 (.500) SILICONE ORING CORD 70 DURO

This Silicone 70A O-Ring Cord, item 0286500, 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 0.5 inch (12.7 mm) cross section, with 1/2 inch nominal CS for cross-reference against common gland and replacement dimensions. Its Silicone material provides flexibility across broad temperature swings and clean sealing applications that require a soft, compliant elastomer. The red 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. Engineers, maintenance teams and purchasing groups can use the listed dimensions to verify fit before selecting the seal for a groove or assembly.
