O-Ring Face Seal

O-Ring Face Seal or ORFS is a thread often used in the most pressure critical hydraulic applications due to its high pressure ratings and non-leak sealing method. ORFS male threads contain an o-ring in the face of the fitting, which offers the best leak-protection of any imperial thread. 

In order to properly identify ORFS threads, please consult the outside and inside diameters of male and female threads respectively. Each of our ORFS fittings contain a thread chart in the description for your convenience. Torque specifications and pressure ratings can be found within our resources as well.
