*568-430 FEP ENCAPSULATED SILICONE

This PTFE/Silicone Core 70A O-Ring, item TES70430, 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 AS568-430; 5.1 inch (129.54 mm) ID x 0.275 inch (6.99 mm) CS; 5.65 inch (143.51 mm) OD, with 5 1/8 inch nominal ID; 1/4 inch nominal CS for cross-reference against common gland and replacement dimensions. Its PTFE encapsulated silicone core material provides 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. 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.
