568-371 FEP ENCAPSULATED VITON ORING

Use item TEV80371 when a PTFE/Viton Core 90A O-Ring is required for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-371; 8.475 inch (215.27 mm) ID x 0.21 inch (5.33 mm) CS; 8.895 inch (225.93 mm) OD, with 8 1/2 inch nominal ID; 3/16 inch nominal CS for cross-reference against common gland and replacement dimensions. The PTFE encapsulated Viton core construction supports 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. 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.
