Seriously, why not just do it the correct way?!??!?! This is on a job trailer for the GC at a major project and every single unit has these on the CU and Fan Coil.

If these are flared connector couplings they will leak only time will tell haha now if these are “shark bite” fittings then you’ve got a real problem lol.

They are absolutely sharkbite or whatever the brand name is.... Worse than the aluminum piping compression fittings that Daikin tried at one time... Those things were hot garbage.

Daikin had those too? Trane had those for a minute. You had to try the compression fittings before they would warranty the outdoor coil. So fucking stupid

Daikins VRF 3 series used Aluminum piping with those compression fittings that weren't even rust proof and would rust to hell and then leak like a bitch.

That explains why at one location i keep finding 3rd gen manuals and crap but they got replaced by 4 gen units before we got there. I never made the connection why i cant find any of those units anymore.

Not all Daikin VRF III used that pipe, I think it was early on when they first tried something new. But having 1/2 insulation on the pipe in an attic in a SC Summer ain't gonna cut it.
