1.78mm PTFE O-Rings

1.78mm PTFE O-Rings are precision-engineered sealing rings designed for industrial applications requiring excellent chemical resistance, high temperature stability, and reliable long-term sealing performance. Manufactured from premium PTFE (Polytetrafluoroethylene), these O-rings provide outstanding resistance to aggressive chemicals, solvents, fuels, and corrosive media.

With a 1.78mm cross section, these PTFE O-Rings are suitable for precision sealing applications where consistent performance and compact installation are required. PTFE material provides excellent temperature resistance, low friction characteristics, non-stick properties, and superior dimensional stability compared with traditional elastomer sealing materials.

Key Features

• High Temperature Performance

 1.78mm PTFE O-Rings maintain sealing reliability in extreme temperature environments and are suitable for demanding industrial applications.

• Excellent Chemical Resistance

 PTFE provides outstanding compatibility with acids, solvents, fuels, and most aggressive chemical media.

• Low Friction Properties

 The low coefficient of friction helps reduce wear and improves performance in dynamic sealing applications.

• Non-Stick Surface Properties

  Minimizes material adhesion and improves sealing reliability.

• Long Service Life

  Maintains sealing performance under harsh industrial conditions.

• Dimensional Stability

  PTFE maintains its shape and sealing properties under high temperature and harsh operating conditions.
