trying to hook a 1/4 pipe port to a JIC hose end, is this the elbow that does 1/4-18 male NPT to 9/16-18 female JIC swivel?
Answer by: Customer Support on May 31, 2025, 8:25 AM
You’ve got the right style. This adapter is a 90 degree elbow with a 1/4-18 male NPT (NPTF external pipe) on one end and a 9/16-18 female JIC 37 degree flare swivel on the other.
Question by: Todd C on Mar 6, 2026, 1:21 PM
Got a 1/4 NPT male port on a manifold block and need to run a 9/16-18 JIC line off it at a right angle. this adapter do that job?
Answer by: Customer Support on Mar 7, 2026, 8:12 PM
That's what this fitting is built for. One end threads into your 1/4-18 NPT port, and the other accepts a 9/16-18 JIC 37 degree flare swivel line, with the whole thing turning 90 degrees so you can route your hose without fighting tight bends or awkward straight-run geometry. The swivel end lets you clock the JIC connection where you need it before you torque everything down, which saves a lot of headache during final assembly.
