Use item HSN90376 when a Hnbr 90A O-Ring is required for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-376; 9.725 inch (247.02 mm) ID x 0.21 inch (5.33 mm) CS; 10.145 inch (257.68 mm) OD, with 9 3/4 inch nominal ID; 3/16 inch nominal CS for cross-reference against common gland and replacement dimensions. The HNBR construction supports abrasion resistance, heat aging resistance and performance in many oil, refrigerant and fluid power applications. It is with a listed temperature range of -40°F (-40°C) to 325°F (163°C), which can help narrow material selection for heat, cold or process exposure. The green 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.
