Customer Reviews for VEVOR 15240mm Mini Split Line Set, 6.4 & 9.5mm O.D Copper Pipes Tubing and Triple-Layer Insulation, for Mini Split Air Conditioning Refrigerant or Heating Pump Equipment & HVAC with Wrapping Strips.
I bought this line set to install my mini split system. The copper line and insulation all appears to be quality product. Took off 1 star because one of the flare fitting on the 3/8 line was slightly too big. It did not allow the nut to spin freely. I ended up having to cut the end off and re-flare it.
