Question: are jic and unf the same?
Answer: JIC / SAE 37 degree / UNF Straight. The only effective difference is that JIC (also known as SAE 37 degree) has a conical seating face (37 degree or 74 degree 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.
