Question by: Lyle H on Dec 12, 2025, 12:17 PM
got a hose end that’s 9/16-18 JIC swivel, what does this adapter thread into on the other side?
Answer by: Customer Support on Dec 13, 2025, 3:34 PM
On the other end it has a 1/4-18 male NPTF pipe thread, so it threads into a female NPTF port and adapts that over to a 9/16-18 female JIC swivel with a 37 degree flare.
