*568-041 FEP ENCAPSULATED SILICONE

Use item TES70041 when a PTFE/Silicone Core 70A O-Ring is required for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-041; 2.989 inch (75.92 mm) ID x 0.07 inch (1.78 mm) CS; 3.129 inch (79.48 mm) OD, with 3 inch nominal ID; 1/16 inch nominal CS for cross-reference against common gland and replacement dimensions. The PTFE encapsulated silicone core construction supports the chemical resistance of a PTFE jacket with the flexibility of a silicone 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 red 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.
