Description
QC Hydraulics ORB (O-ring Boss) fittings or SAE fittings are similar to a JIC fittings without the 37 degree flare. They also have an o-ring for additional sealing.
This fitting is also known as O-Ring Boss (ORB) Recommended by the NFPA for optimal leakage control in medium and high pressure hydraulic systems. The male fitting has a straight thread and O-ring. The female port has a straight thread, a machined surface (minimum spotface) and a chamfer to accept the O-ring.
ORB Hydraulic Adapters available thread configurations:
- ORB JIC Straight Adapters
- ORB JIC Swivel Fittings
- ORB Male Plug
- ORB Hollow Plug
- ORB Elbow
