5.5mm PTFE O-Rings

5.5mm PTFE O-Rings are high-performance sealing rings manufactured for applications requiring outstanding chemical resistance, high temperature capability, and reliable long-term sealing performance. Made from premium PTFE (Polytetrafluoroethylene), these O-Rings maintain excellent stability in aggressive and demanding industrial environments.

With a 5.5mm cross section, PTFE O-Rings provide excellent dimensional stability, extremely low friction, and superior resistance to chemicals, solvents, acids, and corrosive media. Their non-stick surface and low moisture absorption characteristics make them ideal for precision sealing applications.
