This Hnbr 80A O-Ring, item HSN80455, is designed for buyers who need a clear specification match for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-455; 12.975 inch (329.57 mm) ID x 0.275 inch (6.99 mm) CS; 13.525 inch (343.54 mm) OD, with 13 inch nominal ID; 1/4 inch nominal CS for cross-reference against common gland and replacement dimensions. Its HNBR material provides 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. Common purchasing identifiers for this product include the material name, O-ring type, dimensional size, hardness and intended sealing application. Those attributes make the item easier to compare for maintenance, OEM production, MRO replacement and reseller catalog use.
