Review: Good product but be careful of the size when you order. - This did not work for me. Watch out for the sizes. I needed a 1/4" & 3/8" version but misread the "1/4" & 1/2" O.D. 3/8" Thickened PE Insulation". See the difference. Totally my fault. Now, this product I found to be good quality tightly coiled well packaged but not ready to go. You will need to remove the flares, deburr, and redo them properly. I didn't knock off any points because all the professionals I spoke to told me all machine flares can't be trusted and they were right. These were not square and had ripples. Bad juju.
Review: High quality double insulated and grouped line set. - Double insulated and grouped together. The flares looked good to use but, as usual I re-flared for installation. If you don’t have a flare kit, it does come ready to use with nuts and plugs.
