568-455 FEP ENCAPSULATED SILICONE

Item TES70455 is a PTFE/Silicone Core 70A O-Ring built 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. The PTFE encapsulated silicone core compound is selected for 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. Key selection details include material, hardness, product type, cross-section, inside diameter, outside diameter and application. These specification details help customers and resellers compare the part by performance requirements rather than brand name alone.
