Stainless Steel Adapter, 3/4-14 Male NPT To 1-5/16-12 Male JIC 37 deg Flare, Straight

For a 1-inch tube OD JIC connection, that's exactly what this fitting bridges. One end threads into your 3/4-14 male NPT port, and the other end is a 1-5/16-12 male JIC 37 degree flare, which is the correct thread size for 1-inch tube OD JIC fittings. It's a straight adapter, so there's no angle involved. Overall length comes in at 2.11 inches, which is worth accounting for if clearance is tight around that pump port.
