This PTFE/Viton Core 90A O-Ring, item TEV80277, 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 AS568-277; 11.484 inch (291.69 mm) ID x 0.139 inch (3.53 mm) CS; 11.762 inch (298.75 mm) OD, with 11 1/2 inch nominal ID; 1/8 inch nominal CS for cross-reference against common gland and replacement dimensions. Its PTFE encapsulated Viton core material provides the chemical resistance of a PTFE jacket with the elastic recovery of a Viton core. It is with a listed temperature range of -75°F (-59.4°C) to 400°F (204°C), which can help narrow material selection for heat, cold or process exposure. The black 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.
