JIC and SAE BOSS Fittings


JIC (or Joint Industry Council) fittings, defined by SAE J514, are compression fittings machined with a 37 degree flare seating surface and parallel threads.

The Joint Industries Council (JIC), sought to clear the air by standardizing the specifications on this type of fitting by creating the "JIC" fitting standard, a 37-degree fitting with a slightly lower class of thread quality than the military AN version. The SAE went on to adopt this JIC standard as well. Its important to note that the AN and JIC specifications are no longer in existence in most cases.

The majority of the population agrees, the JIC (or SAE) 37 degree hydraulic fittings are generally interchangeable with AN fittings. Keep in mind that JIC fittings are not acceptable for military aviation or aerospace use, but for agricultural equipment, construction equipment, heavy machinery applications or material handling and the like, JIC / SAE adapters are the answer.

An O-ring BOSS seal is a technique for joining two fluid-carrying pipes, hoses, or tubing. In an O-ring BOSS system, a male-threaded part is inserted into a female-threaded part, providing a mechanical seal. This system has the advantage of being able to be tightened mechanically before being sealed.

JIC and BOSS fittings share the same parallel thread size.
