Product Questions & Answers

trying to swap a fitting out, are the ends on this one 1-5/8-12 female JIC 37 flare to 1-1/16-12 male JIC 37 flare, straight?
Question by: Brenda F on Jan 4, 2026, 8:31 AM
For fit confirmation, it is a straight steel union adapter with a 1-5/8-12 Female JIC 37 degree flare on one end and a 1-1/16-12 Male JIC 37 degree flare on the other.

Got a line running 3/4 inch tube and need to step down the JIC fitting on one end, will this adapter handle that kind of size difference between the two connections?
Question by: Ross B on Feb 17, 2026, 7:57 AM
Yeah, that's exactly the situation this part covers. One end is a 1-5/8-12 female JIC 37 degree flare, and the other is a 1-1/16-12 male JIC 37 degree flare, both in the same straight configuration. The 0.75 inch tube OD spec lines up with what you're describing, so if your tubing and existing fittings match those thread sizes, you're good to go.
