Question by: Bonnie M on Sep 25, 2025, 5:43 PM
Does this adapter go from NPTF on one end to a JIC swivel fitting on the other, or did I read the thread specs wrong?
Answer by: Customer Support on Sep 27, 2025, 6:48 AM
You read it right. One end is a 3/4-14 male NPTF thread, which conforms to SAE J476, and the other end is a 1-1/16-12 female JIC swivel with a 37-degree flare, conforming to SAE J514. That combination lets you connect an NPTF-ported component directly to a JIC swivel line without any adapters in between.

What size are the threads on this fitting? Just want to make sure it'll match up with what I've got.
Answer by: Customer Support on May 11, 2025, 8:12 AM
It’s got a 3/4-14 male NPTF thread and a 1-1/16-12 female JIC swivel with a 37-degree flare. Those threads meet SAE J476 and SAE J514 specs, respectively.
Question by: Randy W on Jan 8, 2026, 7:29 AM
got a hose end with a 1-1/16-12 jic swivel on it. will this adapter screw into a 3/4-14 nptf port and still match up right?
Answer by: Customer Support on Jan 10, 2026, 8:34 AM
The threads line up as a 3/4-14 male NPTF on one side (SAE J476) and a 1-1/16-12 female JIC swivel with a 37 degree flare on the other (SAE J514), so it is made to connect that exact NPTF port to that JIC flare connection.
