Product Questions & Answers

trying to swap out an old reducer, will this one go from a 1-5/16-12 female JIC swivel down to a 9/16-18 male JIC?
Question by: Denise C on Dec 30, 2025, 1:53 PM
Match the threads and flare style and you are on the right track. This adapter is a straight reducer with a 1-5/16-12 female JIC 37 degree flare swivel on one end and a 9/16-18 male JIC 37 degree flare on the other.

Will this adapter work to connect a 9/16-18 male JIC to a 1-5/16-12 female JIC?
Question by: Wade B on Apr 27, 2025, 9:10 PM
That's exactly what it's made for. It adapts a 1-5/16-12 female JIC 37-degree flare swivel to a 9/16-18 male JIC 37-degree flare in a straight line.

got a hose end that’s 1-5/16-12 female JIC swivel, and the port i need to hit is 9/16-18 male JIC. is this the right reducer or am i backwards
Question by: Lynn H on Aug 27, 2025, 2:50 PM
Function-wise, it’s the reducer that bridges those two JIC 37 degree flare sizes in a straight adapter. One side is 1-5/16-12 female JIC 37 degree flare swivel, and the other side is 9/16-18 male JIC 37 degree flare, so it matches what you described.

trying to figure out if this'll work as a reducer between my larger JIC line and a smaller fitting downstream, the size jump from 1-5/16-12 down to 9/16-18, is that what this thing does?
Question by: Tommy Y on Aug 16, 2025, 6:38 AM
That's what it handles. The female end accepts a 1-5/16-12 JIC 37 degree flare connection and the male end steps down to a 9/16-18 JIC 37 degree flare. Both ends use the same SAE 37 degree seat angle, so you're getting a straight reducer that keeps the JIC sealing geometry consistent on both sides. The swivel on the female end also makes it easier to thread everything up without fighting the line for alignment.
