ORFS Fittings

SAE O-ring Face Seal Fittings                        

SAE O-ring face seal (ORFS) fittings seal liquids and gases from vacuum to 6000 psig. ORFS fitting can be functional to tubing or pipe. They are “zero clearance” fittings meaning that they can be inserted and removed from systems without cutting or flexing the pipe or tubing. They are very versatile fluid connectors because it works exceptionally well on both fluids and gases.   The makes them ideal for systems requiring frequent maintenance and for valves and other constituents requiring periodic maintenance or replacement.

 

How Soft-Seal O-ring Face Seal Fittings Work

The Soft-Seal fitting gathering consists of four parts: threaded fitting body with O-ring groove, O-ring, nut, and sleeve or tailpiece. The customary O-ring is Buna-N. Other O-rings have been tested as well as are available for special applications.

The fitting assemblage seals when the bottom of the sleeve or tailpiece, which has been permanent to the tubing, compresses the O-ring in the face of the threaded fitting body as the fitting nut is threaded onto the peripheral threads on the fitting body. The threading procedure draws the sleeve into full contact with the face of the fitting. Sleeves or tailpieces can be protected to the tubing either by brazing, welding, or mechanically flanging the tubing.

Features

    • Forgiving assembly – Soft Seal fittings conform well to irregularities in the fitting face or sleeve. So, while proper technique and handling should be observed during assembly, the tube fitting is forgiving of assembly variation.
    • Zero clearance system – No need to spring or pull the tubing to insert or remove a fitting or other components for installation or maintenance.
    • Unlimited remakes – Fittings can be disassembled and reassembled many times. Simply replace the O-ring and tighten to recommended torque.
