got a couple 5/16 tube lines to tie together, is this the right union for that?

For joining two same size tubes, it’s set up for 5/16 in. tube OD on both ends, so it’s a straight tube union meant to connect 5/16 tubing to 5/16 tubing.

got a couple of 5/16 tubes I need to join end to end, this the right fitting for that?

That's what this union is built for. Both ends are sized for 5/16 in. tube OD, so you're making a straight inline connection between two same-size tubes. The overall length runs 1.180 in. and the hex comes in at 0.562 in., so it's a compact fitting that won't take up much room in a tight hydraulic connections run.
