568-403 URETHANE 70 DURO ORINGS

Use item U70403 when an Urethane 70A O-Ring is required for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-403; 1.725 inch (43.82 mm) ID x 0.275 inch (6.99 mm) CS; 2.275 inch (57.79 mm) OD, with 1 3/4 inch nominal ID; 1/4 inch nominal CS for cross-reference against common gland and replacement dimensions. The Urethane construction supports 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. Important product identifiers include O-rings, replacement seals, fluid sealing, material compatibility and dimensional fit. It supports customer comparison, distributor cataloging and specification-based selection without relying on pricing, availability or shipping claims.
