PTFE and Teflon® Coated O-Rings

Discover the Benefits of PTFE, Teflon®, and Parylene Coated O-Rings.

O-ring Coatings

Surface coating can make the difference between a smooth running machine and frequent repairs. Damage to O-Rings can bring machinery to a halt and that means a loss of productivity and reduced profits. Increase the life of vital parts by adding surface coating.

O-Ring surface coatings are available in a wide variety of colors with Dark Blue being the most common.


Surface Coating Benefits

  • Easier installation - added lubricity lessens assembly time
  • Easier identification of parts by color coding - distinguish by size or material
  • Extend wear life - less corrosion, less degradation, less downtime
  • Resist contamination from dirt and debris - no messy oil-based lubricants
  • Reduce risk of repetitive injuries (carpal tunnel syndrome)

Surface Coating Types and Applications

PTFE (and Teflon®) Coated O-Rings

  • Offers excellent chemical resistance, low friction, and high-temperature tolerance. Suitable for dynamic and high-temperature applications.
  • Best for applications requiring low friction, high-temperature resistance, and chemical resistance, such as in the automotive, aerospace, and chemical processing industries.

Parylene Coated O-Rings

  • Provides excellent chemical resistance, electrical insulation, biocompatibility, and a superior moisture barrier. Ideal for medical, electronic, and highly sensitive applications.
  • Ideal for applications needing excellent chemical resistance, biocompatibility, electrical insulation, and moisture barriers, such as in medical devices, electronics, and aerospace components.
