Steel Adapter, 7/16-20 Male JIC 37 deg Flare To 1/4-19 Male JIS 30 deg Flare Seat (BSPP Thread), Straight

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.

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.
