.138 ID X .218 OD SILICONE TUBING

This Silicone 50A O-Ring Cord, item 0286T.138IDX.218OD, 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 0.138 inch (3.51 mm) cross section, giving buyers a clear dimensional reference for matching the seal to the groove, shaft or bore. Its Silicone material provides 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 formed 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.
