568-376 PTFE ORINGS FDA

Item TFE376 is a PTFE 55D O-Ring built for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-376; 9.725 inch (247.02 mm) ID x 0.21 inch (5.33 mm) CS; 10.145 inch (257.68 mm) OD, with 9 3/4 inch nominal ID; 3/16 inch nominal CS for cross-reference against common gland and replacement dimensions. The PTFE compound is selected for chemical resistance, low friction and low surface energy in demanding static sealing applications. It is with a listed temperature range of -65°F (-53.9°C) to 500°F (260°C), which can help narrow material selection for heat, cold or process exposure. The white 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.
