got a little air setup with 1/8 npt lines. is this regulator the right size and what kinda pressure can i dial in

For compact air hydraulic connections, it matches up with 1/8 NPT ports and it adjusts across a 0 to 140 psi spring range. It also comes with a gauge, so you can set and keep an eye on the downstream pressure without guessing.
