4mm PTFE O-Rings

4mm PTFE O-Rings are high-performance sealing rings designed for applications requiring superior chemical resistance, high temperature capability, and reliable sealing performance. Made from premium PTFE (Polytetrafluoroethylene), these O-Rings maintain excellent stability in aggressive chemical environments and demanding industrial conditions.

With a 4mm cross section, PTFE O-Rings provide low friction operation, excellent dimensional stability, and resistance to most chemicals, solvents, acids, and corrosive media. Their non-stick surface and low moisture absorption make them suitable for precision sealing applications where durability and reliability are critical.
