5.5 MM (.216) SILICONE O-RING CORD 70 DU

Use item 0M286S5.5 when a Silicone 70A O-Ring Cord is required for custom O-ring fabrication, spliced seals, field repairs and nonstandard groove diameters. The item is specified by 0.216 inch (5.5 mm) cross section, with 5 1/2 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 -80°F (-62.2°C) to 450°F (232°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.
