568-243 FEP ENCAPSULATED VITON ORING

Use item TEV80243 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 AS568-243; 4.109 inch (104.37 mm) ID x 0.139 inch (3.53 mm) CS; 4.387 inch (111.43 mm) OD, with 4 1/8 inch nominal ID; 1/8 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.
