Product Questions & Answers

i got a hose end that’s 1-5/16-12 JIC, will this adapter screw right onto it?

Question by: Ross T on Feb 17, 2026, 9:09 PM

The JIC side on this adapter is a 1-5/16-12 male SAE 37 degree flare, so it matches a hose end or fitting with a 1-5/16-12 female JIC 37 degree flare.

got a port that’s 3/4-14 npt and i need to go over to a jic flare line. is this the right adapter or am i mixin stuff up

Question by: Brett H on Jun 7, 2025, 7:43 AM

Function-wise, it’s a straight adapter made to transition from a 3/4-14 male NPT pipe thread to a 1-5/16-12 male JIC 37 degree flare connection. If those two thread callouts match what you’re tying together, this is the correct style of fitting.
