Male JIC Measurements To ensure the correct identification/measurement for male JIC threads, ensure that you are measuring the outer diameter (O.D.) of the fitting. Female JIC Measurements To ensure the correct identification/measurement for female JIC threads, ensure that you are measuring the inner diameter (I.D.) of the fitting. Male SAE/ORB Measurements To ensure the correct identification/measurement for male SAE/ORB threads, ensure that you are measuring the outer diameter (O.D.) of the fitting. Female SAE/ORB Measurements To ensure the correct identification/measurement for female SAE/ORB threads, ensure that you are measuring the inner diameter (I.D.) of the fitting. JIC Male JIC Female SAE/ORB Male SAE/ORB Female Thread Guide SAE Straight Thread O-Ring (ORB) SAE J1926-1 and ISO 11296-1 Conforms to MS16142, UN/UNF Threads This port connection (sometimes called O-Ring Boss) is recommended for optimum leakage control in medium and high pressure hydraulic systems. The male connector has a straight thread and an O-ring. The female port has a straight thread, a machined surface (minimal spotface) and a chamfer to accept the O-ring. The seal takes place by compressing the O-ring into the chamfer. The threads hold the connection mechanically. JIC 37° Flare SAE J514 Originally named for the Joint Industrial Commission (JIC), this connection is very common in fluid power systems. Both the male and female halves of this connection have 37° seats. The seal takes place by establishing a line of contact between the male flare and the female cone seat. The threads hold the connection mechanically. This connection is also commonly used with flared tubing.
