got two pieces of 3/4 tube i need to join up without messing with threads. is this the right kind of fitting for that

For joining two tube ends without welding or threading, a 3/4 compression union like this is the standard approach. It makes a mechanical seal on the tubing, so you can connect the two ends and still take it back apart later if you need to service the line.

we got some tubing runs that need to be joined up without any welding involved, this the kind of fitting that handles that?

That's what compression unions are built for. You sleeve the tubing ends into each side, tighten down the compression nuts, and the ferrules seat against the tube to form a sealed mechanical connection. No torch, no threading, no fuss. It's a practical solution for hydraulic lines, instrumentation tubing, and general fluid handling circuits where you need a solid joint but welding just isn't an option or isn't practical.
