WebSubstituting AN Fitting for JIC. If you are going to substitute an AN fitting for a JIC component, you will have to use a JIC or AN union, which is a UNF thread in which the male has a convex seat and the female has a concave seat. Importantly, the seat on both AN and JIC is 78°. The table below lists AN thread and size information along with ... WebUNJF Thread Series, is suitable for the production of bolts, screws, and nuts for aerospace applications where the Root Radius is controlled. External threads of this series have greater tensile stress area than comparable sizes of the Coarse series. The Fine series is suitable when the resistance to stripping of both external.

Technically the fittings should not be interchanged, however, the only difference between -AN and JIC is the thread class. WebSAE J514 JIC/37˚ Hydraulic This connection is very common in fluid power sys-tems. Both the male and female halves of the con-nections have 37° seats. The seal takes place by establishing a line of contact between the male flare and the female cone seat. The threads hold the con-nection mechanically. error thinking
