3mm PTFE O-Rings

3mm PTFE O-Rings are high-performance sealing components designed for extreme industrial environments requiring excellent chemical resistance, high temperature capability, and low friction operation.

Manufactured from premium PTFE (Polytetrafluoroethylene), these sealing rings provide outstanding resistance to aggressive chemicals, solvents, fuels, acids, and hydraulic fluids. The 3mm cross section offers reliable sealing performance for a wide range of static and dynamic sealing applications.

PTFE O-Rings are widely used in chemical processing equipment, pumps, valves, hydraulic systems, semiconductor equipment, aerospace components, and other applications where conventional rubber O-rings may not withstand harsh operating conditions.
