O-Ring Face Seal

- As the name implies, ORFS, or (O-ring Face Seal) fittings incorporate an O-ring at the face of the fitting. Made to SAE J1453 standard, ORFS connections are commonly manufactured in carbon, nickel plated carbon & Stainless steel and typically use Buna-N or Viton, 90 Durometer O-rings that seat into a groove in the face of the fitting. This is known as an elastomeric seal.

- The seal is created when the o-ring compresses between the o-ring face of the fitting and flat face of the mating ORFS fitting or the formed tube. When the connection is tightened the O-ring compresses against a flat face of mating fitting or tube.
