.375 (3/8) SILICONE SPONGE CORD

Use item 0290375 when a Silicone O-Ring Cord is required for custom O-ring fabrication, spliced seals, field repairs and nonstandard groove diameters. The item is specified by 0.375 inch (9.53 mm) cross section, with 3/8 inch nominal CS for cross-reference against common gland and replacement dimensions. The Silicone construction supports flexibility across broad temperature swings and clean sealing applications that require a soft, compliant elastomer. It is with a listed temperature range of -72°F (-60°C) to 392°F (200°C), which can help narrow material selection for heat, cold or process exposure. 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. 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.
