*568-220 URETHANE 90 ORINGS - PREM GRADE

Item U90220 is an Urethane 90A O-Ring built for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-220; 1.359 inch (34.52 mm) ID x 0.139 inch (3.53 mm) CS; 1.637 inch (41.58 mm) OD, with 1 3/8 inch nominal ID; 1/8 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.
