The female and male threads on 37° Flare seat are all produced in accordance to UN/UNF series threads. JIC 37° Flare seat of hydraulic fittings normally used in United States markets. JIS specification is defined by Japanese Industrial Standards. Threads on JIS B8363 30° Flare hydraulic fittings, are manufactured according to the standard BSPP(PF/G). JIC and JIS fittings are not interchangeable as they are aimed for two different tubing connection systems.


BS B5200 60° Cone hydraulic tube fittings are commonly used in European countries. The external and internal threads are produced based on the standard of BSPP(PF/G) male parallel 60° cone seat.
