.210" C/S (3/16" NOMINAL) (5.33 MM)

Item 0281210 is an Aflas 75A O-Ring Cord built for custom O-ring fabrication, spliced seals, field repairs and nonstandard groove diameters. The item is specified by 0.21 inch (5.33 mm) cross section, with 3/16 inch nominal CS for cross-reference against common gland and replacement dimensions. The Aflas compound is selected for high heat, amines, oils and demanding chemical environments found in process, oilfield and power applications. It is with a listed temperature range of -25°F (-3.9°C) to 450°F (232°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.
