Question by: Shawn B on Nov 17, 2025, 6:33 AM
Will this adapter work to connect a Japanese fitting to something using JIC?
Answer by: Customer Support on Nov 18, 2025, 3:49 PM
This adapter is designed to connect a 7/16-20 Male JIC 37-degree flare fitting to a 1/4-19 Male JIS 30-degree flare seat with BSPP threading. It's meant for bridging those two specific types.
Question by: Duane R on Mar 18, 2026, 9:28 PM
got a piece of equipment that's running JIC on one end and JIS on the other, this the right part to tie those together?
Answer by: Customer Support on Mar 20, 2026, 9:23 AM
That's what this adapter is built for. One end is a 7/16-20 Male JIC 37-degree flare and the other is a 1/4-19 Male JIS 30-degree flare seat with BSPP threading. Both ends are male, so you'd be threading this into female JIC and female JIS ports respectively. Adaptall makes it straight, no angle, so it works clean in tight runs where you just need a direct bridge between those two standards.
