5/8 SQUARE BUNA 70 O-RING CORD

Item 0296625 is a Buna-N NBR 70A O-Ring Cord built for custom O-ring fabrication, spliced seals, field repairs and nonstandard groove diameters. The item is specified by 0.625 inch (15.88 mm) cross section, with 5/8 inch nominal CS for cross-reference against common gland and replacement dimensions. The Buna-N nitrile (NBR) compound is selected for oil, grease, fuel and general hydraulic fluid resistance in common industrial equipment. The black color and square 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. Engineers, maintenance teams and purchasing groups can use the listed dimensions to verify fit before selecting the seal for a groove or assembly.
