Customer Reviews for VEVOR 25FT Mini Split Line Set, 6.4 & 12.7mm O.D Copper Pipes Tubing and Triple-Layer Insulation, for Air Conditioning or Heating Pump Equipment & HVAC with Rich Accessories (27ft Connection Cable)
The 1/4" inch line was just a bit to small in diameter. I was not able to re-flare in my flaring tool. I had to wrap the 1/4" copper line with some sand paper so the flaring tool would work
I ordered this replacement set after accidentally damaging my first one. These are working perfect. My ac is working just as intended, and I had a nice cool and comfortable night thanks to these.
