Specialty O-Rings & Seals

PFI has become the trusted source for the highest quality manufacturer of specialty O-Rings and Seals of all types and sizes. While we manufacture seals and o-rings out of many materials, PTFE is by far the most popular.

PTFE Seals and O-Rings offer extreme temperature, high pressure, and chemically inert properties for the most demanding applications. Some of the benefits of PTFE are as follows:

  • Lowest coefficient of friction
  • Chemical resistance
  • Heat & cold resistance (up to 500°)
  • Flexible
  • Non-toxic
  • Odorless & tasteless
  • Can be sterilized
  • Detergent-proof & steam-proof
  • FDA approved for food applications

PTFE is recommended for:

  • Chemical environments
  • Use in acidic or basic environments
  • Sealing of moving or sliding surfaces
  • PTFE is not recommended for:

    • Low compression vacuum sealing flanges
    • High vacuum seals
    • High temperature steam
