568-328 URETHANE 70 DURO ORINGS

Item U70328 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 AS568-328; 1.85 inch (46.99 mm) ID x 0.21 inch (5.33 mm) CS; 2.27 inch (57.66 mm) OD, with 1 7/8 inch nominal ID; 3/16 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.
