Great deal but compared to the more expensive ICOOL branded linesets, the insulation is not as thick and the copper seems to be a slightly thinner gauge.I used 2 sets of the this lineset to run to indoor mounted air handlers for mini split heatpump, had minor issues with using a torque spanner wrench with the 3/8" line slight twisting requiring me to reflare it, flaring is somewhat hard to do a single flare so I ended up doing a double flare for strong connection to the mating end. Recommend support the line straight in to the flare as your torque it down to specification and use nylok blue on the mating side of the flare and a thin finger rub of it for the back side where the nut meets up.Also the 3/8" cannot be bend as much as the 1/4", I STRONGLY RECOMMEND doing no more than 45 degree bend then moving down slightly and doing another 45 degree bend. I had flat side and kinks in the line from the first time with bending tool, and the acceptable second time, I had starts of minor ripples in the line but still very much usable line.Great deal but you might have to re-flare if it twists or kinks which is possible with this thinner tubing.
