568-452 PTFE ORINGS FDA

This PTFE 55D O-Ring, item TFE452, 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 AS568-452; 11.475 inch (291.47 mm) ID x 0.275 inch (6.99 mm) CS; 12.025 inch (305.44 mm) OD, with 11 1/2 inch nominal ID; 1/4 inch nominal CS for cross-reference against common gland and replacement dimensions. Its PTFE material provides 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. 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.
