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?
Answer by: Customer Support on Jan 6, 2026, 6:25 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?
Answer by: Customer Support on Feb 18, 2026, 3:05 PM
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.
