568-920 PTFE ORINGS FDA

Use item TFE920 when a PTFE 55D O-Ring is required for industrial fluid sealing, equipment repair, pumps, valves, cylinders and general maintenance applications. The item is specified by AS568-920; 1.475 inch (37.47 mm) ID x 0.118 inch (3 mm) CS; 1.711 inch (43.46 mm) OD, with 1 1/4 inch nominal ID; 1/8 inch nominal CS for cross-reference against common gland and replacement dimensions. The PTFE construction supports 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. 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.
