Question by: Tommy T on Feb 22, 2026, 6:50 AM
Will this adapter work to connect a JIC flared fitting to a BSPP threaded port?
Answer by: Customer Support on Feb 23, 2026, 11:47 AM
This adapter is designed specifically for that purpose, connecting a 9/16-18 male JIC 37 degree flare to a 3/8-19 female JIS 30 degree flare seat, which is a BSPP thread.
Question by: Daryl S on Mar 14, 2026, 1:38 PM
got a piece of equipment with a JIS port on it and need to tie into a JIC line -- this straight adapter the right call for that?
Answer by: Customer Support on Mar 16, 2026, 6:51 AM
That's what this fitting is built for. One end is a 9/16-18 male JIC with a 37-degree flare, and the other is a 3/8-19 female JIS with a 30-degree flare seat on a BSPP thread. So if you've got a JIC line coming in and a JIS port on your equipment, this adapter bridges that gap in a straight configuration. No thread sealant is needed on this one, which keeps the install clean and straightforward.
