Brass Adapter, 1/4-18 Male NPT To 9/16-18 Male JIC 37 deg Flare, 90 deg Elbow

For that kind of hookup, it matches the common combo you’re describing: one end is 1/4-18 male NPTF and the other end is 9/16-18 male JIC with a 37 degree flare, and it’s built as a 90 degree elbow for tighter routing.

Use-case-first: You could use this adapter in that way, provided the pump has a 1/4-18 male NPT port and your gauge has a 9/16-18 male JIC 37-degree flare connection.

For that exact situation, yes. One end is 1/4-18 male NPT, which threads into standard pipe thread ports, and the other end is 9/16-18 male JIC with a 37-degree flare seat. The 90-degree elbow body handles the direction change, so you're not forcing a bend into the line itself. It's brass, made by Eaton Aeroquip, and the NPTF threading on the pipe end is precision enough that you typically won't need thread sealant on either connection.
