Male Jic X Male Bspt

Function-wise it is a straight steel adapter with a 5/8 inch male JIC on one side (7/8 - 14 UNF thread) and a 3/4 inch male BSPT on the other side (R 3/4 - 14 thread). It is meant for connecting those two thread types in-line.

That's what this fitting is built for. One end is a 7/8-14 UNF male JIC thread, which corresponds to a 5/8" JIC size, and the other end is an R 3/4-14 male BSPT thread. Both ends are male, so you'd be threading each side into female ports or couplings on your existing lines. The body is steel and runs straight through with no angle, so it keeps your hydraulic connections clean and in-line.

Yes, this is a straight steel adapter fitting specifically designed to connect a 5/8" male JIC end to a 3/4" male Bspt end.
