Steel Adapter, 1/2-14 Male NPT To 3/4-16 Female JIC 37 deg Flare Swivel, 90 deg Elbow

The female end is a 3/4-16 SAE 37 degree flare swivel (JIC style), and the other end is a 1/2-14 male NPTF pipe thread. It is a 90 degree elbow, so it turns the connection at a right angle.

For that setup, this adapter matches 1/2-14 male NPT on one end and 3/4-16 female JIC 37 degree flare swivel on the other, and it is a 90 degree elbow. It is meant for connecting an NPTF external pipe thread to an SAE 37 degree flare swivel connection.

Marine, military, chemical processing, pulp and paper, food and beverage, and offshore drilling are all listed applications for this fitting. It's an Eaton Aeroquip 2250 Series piece, so it's built for environments where connection reliability matters. If your operation falls into any of those categories, this adapter is a reasonable candidate for your system.
