These three thread types/ forms share the same dimensions and thread pitches in all sizes. They  broadly used for refrigeration and air conditioning plants  The only effective difference is that JIC (also known as SAE 37°) has a conical seating face (37° or 74° total angle) and UNF straight has a flat seat – sealing being effected by use of a washer. Male JIC fittings have a convex cone, female fittings a concave cone. JIC (also called AN from its American Army/Navy usage) is the most widely-used thread type in competition or high performance plumbing. Most hose ends are made to this specification. (There is, also, an SAE45° threadform which has a 45° conical seat. It shares the same dimensions as JIC except for the angle of its seat and in its 1–1/16 size when it has 14 threads per inch (TPI) .
