3.55mm PTFE O-Rings

Product Overview

3.55mm PTFE O-Rings are high-performance sealing rings designed for industrial applications requiring superior chemical resistance, high temperature capability, and long-term sealing reliability. Manufactured from premium PTFE (Polytetrafluoroethylene), these O-Rings maintain excellent stability in harsh operating environments.

Featuring a 3.55mm cross section, PTFE O-Rings provide extremely low friction, excellent dimensional stability, and outstanding resistance to aggressive chemicals, solvents, acids, and corrosive media. Their non-stick surface and low moisture absorption characteristics make them suitable for precision sealing applications.
