3.1mm PTFE O-Rings

3.1mm PTFE O-Rings are high-performance sealing components designed for industrial applications requiring superior chemical resistance, high temperature capability, and reliable sealing performance.

Manufactured from premium PTFE (Polytetrafluoroethylene), these O-rings provide excellent resistance to aggressive chemicals, acids, solvents, fuels, and hydraulic fluids. The 3.1mm cross section delivers stable sealing performance for equipment operating under demanding conditions.

PTFE O-Rings are widely used as an alternative to traditional rubber sealing rings in applications where extreme temperatures, chemical exposure, and low friction performance are required.
