JIC 37° FLARE ADAPTERS

In general, tube fittings were first designed to allow connections between components using steel or copper tubing. In North America, the tubing was flared at the end and secured with a threaded nut and sometimes a back-up sleeve. Therefore, this type of fitting is most commonly referred to as a flare fitting, either according to JIC (Joint Industrial Council) which calls for a 37° flare for steel tubing, or SAE (Society of Automotive Engineers) which specifies a 45° flare on the softer copper tubing most commonly found in low pressure automotive applications. Today, JIC fittings are widespread in hydraulic applications, while SAE adapters are commonly brass and are usually confined to truck and plumbing markets. Flare fittings are called by the size of tubing they connect to rather than the thread dimension. For example, a JIC in size -08 is designed to connect to a 1 ⁄ 2 " O.D. tube, but the fitting actually measures 3 ⁄ 4 " on the outside of the thread. JIC and SAE thread dimensions are the exact same in sizes -02, -03, -04, -05, -08, and -10, and so will often serve quite well when interchanged in low pressure applications as only the seat angle varies. However in sizes -06, -12, and in larger sizes they will not interchange. Flare fittings can be readily identified by measuring the male thread dimension, the pitch (number of threads per inch), and the flare angle.
