I'm installing my own mini-split consisting of a Fujitsu wall mount unit on an interior wall. The unit didn't come with a short line to pass through the wall so I need to cut a small section of the lineset to install the wall unit and make the a union connection in the basement to the longer line that will run outside. I don't think I can run a continuous line.

R410a requires special flared unions but I can't fine a supplier for the unions,or at least not union that are specifically called out for R410a use. Everything I find is for fuel gas. Can anyone here help me out?

A professional forum would blast a common homeowner but I just don't trust/can't afford the hacks around here.
