jic hydraulic fittings systems

jic swivel fittings, defined by the SAE adapter standards, are a type of flare fitting machined with a 37-degree flare seating surface.  JIC (Joint Industry Council) fittings are widely used in fuel delivery and fluid power applications, especially where high pressure (up to 10,000 psi) is involved. JIC fittings are dimensionally identical to AN (Aeronautical-Navy) fittings, but are produced to less exacting tolerances and are generally less costly.  SAE 45-degree flare fittings are similar in appearance, but are not interchangeable though dash sizes 2, 3, 4, 5, 8, 10, 14, and 16 share the same thread size. Some couplings may have dual machined seats for both 37-degree and 45-degree flare seats. The only difference is milimeter thread sizes while JIS use a BSP (British Standard Pipe) thread. jic hydraulic fittings systems have three components that make a tubing assembly: fitting, flare nut, and sleeve.  As with other flared connection systems, the seal is achieved through metal-to-metal contact between the finished surface of the fitting nose and the inside diameter of the flared tubing.  The sleeve is used to evenly distribute the compressive forces of the flare nut to the flared end of the tube.
