O-ring face seal type fitting, it also known as ORFS fittings, which has an o-ring in the face of the fitting to help make a better seal. ORFS adapter fittings use a straight thread and have a machined groove in the face of the male fitting to accept an O-ring (of either Buna- N or FKM Viton material), which are designed to eliminate leaks in high pressure hydraulic systems.
O-ring face seal fittings can eliminate leaks in hydraulic systems at operating pressures as high as 6,000 PSI. They are designed specifically for applications where elastomeric seals are acceptable to overcome leakage and variations in assembly procedures. The fittings can be easily connected to a range of tubing grades by silver brazing. In addition, ORFS fittings can be disassembled and reassembled in the field to facilitate replacement of the O-ring or the entire assembly.
