568-429 URETHANE 70 DURO ORINGS

Item U70429 is an Urethane 70A O-Ring built for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-429; 4.975 inch (126.37 mm) ID x 0.275 inch (6.99 mm) CS; 5.525 inch (140.34 mm) OD, with 5 inch nominal ID; 1/4 inch nominal CS for cross-reference against common gland and replacement dimensions. The Urethane compound is selected for abrasion resistance, cut resistance and extrusion resistance in dynamic hydraulic and pneumatic sealing applications. It is with a listed temperature range of -65°F (-53.9°C) to 200°F (93.3°C), which can help narrow material selection for heat, cold or process exposure. The clear color and round profile provide a practical visual identifier during receiving, stocking and installation. This standard industrial O-ring can be used across compatible static and dynamic sealing applications in pumps, valves, cylinders and assemblies. The each-unit format supports precise replacement, kitting, resale and job-specific purchasing. 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.
