Hydraulic Fittings Identification Chart
- Due to common threads, mismatching can happen and could result in leaks and pressure loss
- Be sure to verify which style and use dash sizes when ordering replacement parts
Thread Styles
-NPT is easily recognizable as tapered National Pipe Thread. It is not recommended for hydraulic systems
but does exist on some agriculture equipment. Teflon tape is required.
-SAE ORB
is 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 spot face) and a chamfer to accept the O-ring. The seal takes place by compressing the O-
ring in the chamfer. The threads hold the connection mechanically.
-JIC 37 Degree Flare
fittings have a 37° cone seat on the female adapter and a 37° flare on the male adapter.
This cone seat and flare allows for a complete mechanical seal between the male and female fitting. Teflon
tape on threads is not required .
-
ORFS (O-Ring Face Seal) adapter fittings use a straight thread and have a machined groove in the face of the
male fitting to accept the O-ring. This O-ring is compressed against the flat face of the female fitting for a leak
proof connection. ORFS are one of the newest types of hydraulic fittings.
