Steel Adapter, 1/4-18 Female NPT To 7/16-20 Male JIC 37 deg Flare, Straight Bulkhead

For a straight bulkhead pass-through, this adapter matches 1/4-18 female NPT on one end and 7/16-20 male JIC 37 degree flare on the other.

That's exactly what this fitting is built for. One end threads into a 1/4-18 NPT port, and the other side puts out a 7/16-20 male JIC 37-degree flare connection. The bulkhead design means it mounts through a panel or plate and keeps both sides accessible, so you can tie in your JIC line on the flare end without any awkward routing. Solid steel construction from Brennan Industries, so it'll hold up in a working hydraulic or pneumatic system without leaking down on you.

This steel adapter is indeed designed to make that connection, going from a 1/4-18 female NPT to a 7/16-20 male JIC 37 degree flare, which works with a 0.25-inch outer diameter tube.

The threads on this adapter are 1/4-18 female NPT on one side and 7/16-20 male JIC 37 degree flare on the other, and it matches a 0.25 inch tube O.D. on the JIC side.
