Brass Adapter, 1/4-18 Male NPT To 7/16-20 Male JIC 37 deg Flare, 90 deg Elbow

For a right angle hookup, it gives you a 90 degree elbow with a 1/4-18 male NPT connection on one end and a 7/16-20 male JIC 37 degree flare connection on the other.

That's what this fitting is built for. One end is 1/4-18 Male NPT, the other is 7/16-20 Male JIC with a 37 degree flare, and the 90 degree elbow body lets you make that direction change right at the port. Brass construction makes it a solid pick for a lot of common fluid systems, and the Eaton Aeroquip 2024 series is well regarded for consistent thread quality on both ends.

This Eaton Aeroquip adapter is often used in chemical processing, so it should be suitable for that application, but it's always best to check the fluid compatibility document to be sure it'll work with the specific chemicals you're using.
