SAE thread JIC fitting size chart

Date:Apr 02, 2020

SAE J514 37° Flare (also known as JIC)

This is a very common connection in Hydraulic fluid power applications. Both the JIC male and JIC female fittings have 37° seat with straight threads. The seal takes place between the male flare and female cone seat. The straight threads of the each half hold the connection together mechanically.

Note: While most SAE J514 threads look identical to SAE 45º flare threads, their seating angles do not match.
