Product Questions & Answers

i got a hose end that’s 9/16-18 JIC, will this adapter mate up to that and still give me NPT on the other side?

Question by: Bobby G on Jun 26, 2025, 6:29 PM

On the JIC side, you get a 9/16-18 male JIC 37 degree flare. The other end is a 3/8-18 female NPT, so it’s meant to bridge a 9/16-18 JIC connection over to a 3/8-18 NPT threaded connection.

got a 3/8 female NPT port on a panel and need to run a JIC line off it, this the right adapter to bridge that gap?

Question by: Duane R on Nov 25, 2025, 11:23 AM

That's exactly what this fitting is built for. One end threads into a 3/8-18 female NPT port, and the other presents a 9/16-18 male JIC 37-degree flare for your JIC line connection. The bulkhead design also means it's meant to mount through a panel or wall, so if you're routing a line through sheet metal or a housing, it'll seat and lock in place securely rather than just floating in line.
