HGW O-Ring Face Seal fittings and adapters support SAE J1453 flat-face hydraulic connections. The category includes ORFS unions, elbows, tees, crosses, swivels, bulkheads, caps, plugs, sleeves, nuts, and conversion fittings.
In an ORFS connection, an O-ring retained in the male face is compressed against the flat sealing face of the mating female swivel. The straight threads draw the two faces together but do not provide the primary seal. Clean, undamaged faces and the correct O-ring are essential, making ORFS a practical choice where vibration control, repeatable assembly, and external leakage reduction are priorities.
HGW ORFS series include straight, 45°, 90°, tee, cross, bulkhead, swivel, and adjustable-port configurations. Conversion options connect ORFS to JIC, NPTF, ORB, BSPP, BSPT, metric ED-seal, and ISO 6149 ports, allowing equipment to retain a face-seal line connection while adapting to the port standard used by a pump, valve, manifold, or cylinder.
Materials
HGW ORFS fittings are offered primarily in steel and stainless steel, with material availability varying by series and size. Confirm the exact material, finish, O-ring specification, dimensions, and pressure rating on the selected item.
Common Applications
Mobile equipment exposed to vibration and pressure cycling
Leak-sensitive hydraulic lines and service points
Construction, agricultural, and material-handling machinery
Hydraulic manifolds, pumps, valves, and cylinders
Assemblies that are disconnected and serviced periodically
Conversions from ORFS lines to common port standards
