Got a hydraulic line running BSPP on one end and need to tie into an O-ring boss port on the other side, this straight adapter do that job?

That's what this fitting is built for. One end is a male G 1/2-14 BSPP thread, the other is a female 3/4-16 UNF O-Ring Boss port. Both sides are 1/2" size, so you're connecting two same-size lines without any reducers or extra fittings in between. The straight configuration keeps things clean and inline, and at 40.3mm long it's a compact piece that won't eat up much space in a tight hydraulic connections run.

On one side you have a male BSPP thread with a G 1/2 - 14 callout, and on the other side it’s a female O-Ring Boss (ORB-SAE) thread with a 3/4 - 16 UNF callout.
