Steel Adapter, 1-11-1/2 Male NPT Run To 1-5/16-12 Male JIC 37 deg Flare Run & Branch, Tee

For tying those two connection styles together, yes. It is a steel tee adapter with a 1-11-1/2 male NPTF on the run and a 1-5/16-12 male JIC SAE 37 degree flare on the run and branch.

That's exactly what this fitting is built for. The run ports are 1-11/2 male NPT and the branch comes off as 1-5/16-12 male JIC 37 degree flare, so you've got both connection types covered in one piece. It's a steel tee from Eaton Aeroquip's 2028 series, meant for hydraulic, instrumentation, and chemical processing lines. The NPT side threads into a female pipe port and the JIC end connects to a standard 37 degree flare fitting. Solid choice for splitting a line where you've got mismatched thread types on either side.

It's designed for hydraulic, instrumentation, and chemical processing systems, so it should be suitable for a tractor's hydraulic system, assuming the pressure and media are compatible.
