Product Questions & Answers

Does the JIC side on this adapter run a 1-1/16-12 thread, or am I looking at the wrong part number for my fitting?

Question by: Dwayne S on Mar 12, 2026, 1:55 PM

Yeah, that's the right one. Thread B1 is a 1-1/16-12 male JIC with a 37-degree flare, built to SAE J514 spec. The NPTF side runs 3/4-14, so if your port is a 3/4 female NPT or NPTF, this adapter bridges the two without any additional fittings in between.

Just want to make sure I'm understanding right, this fitting has a male JIC on one end and a male NPTF on the other?

Question by: Lyle J on Jun 15, 2025, 8:42 PM

That's correct. One side features a 1-1/16-12 male JIC SAE 37-degree flare according to SAE J514 standards. The other is a 3/4-14 male NPTF adhering to SAE J476 specs.

got a hose end that’s 1-1/16-12 JIC 37 degree flare. will this adapter screw right onto it?

For a JIC flare connection, Thread B1 on this adapter is a 1-1/16-12 male JIC SAE 37 degree flare built to SAE J514, so it mates with a matching female JIC 37 degree flare of the same size.
