DuctlessAire Insulated Copper Twin Line Set for Ductless Mini Split Air Conditioner and Heat Pump System - Insulation Copper Pipe Coil Tubing for HVAC, AC & More - Universal Cover (25ft, 1/4 x 1/2 in)

When a product is done right for the task; it's really hard for it to be wrong. This is a line-set designed for mini-split AC/HP applications & there's nothing wrong with it, whatsoever. It is exactly what I expected it to be.I will say (should anyone be wondering) that the fittings are the heavier-duty style and much less prone to splitting due to water leaching into the bell & freezing. The insulation on this type of line-set is easy to work with & to pull through holes than the old-school foam type, and since it's melded together, it really suits Mini-split installations.I was not expecting to be blown away, and I wasn't; but that said... there's nothing bad to say either.Good product, packed right, shipped fairly quickly, and matched it's purpose quite well. It was just as advertised, and I had no issues. Overall, nothing bad to say > good review!

Good product

This arrived in slightly damaged packaging with some small dents in some of the insulation, but it worked well. I installed it in a cooper&hunter ductless mini-split, used nylog blue lubricant on the threads and flairs, and torqued it to the specs in the installation manual with a digital torque wrench and it seems to work well with no leaks (the unit has been running well for over 10 days now.) I ended up not using the plastic hole guide thingy as I didn't have a hole saw large enough for it. Instead I 3d-printed one that was 2.25" O.D. with 2mm thick walls. The tubing was a tight squeeze, but doable. I also only needed one of the 4 included rolls of rubbery non-sticky tape stuff. The line hiding kit I purchased (not from ductless air but one that's half the price) didn't allow for a 4" bending radius. This is the reason for the ball of duct tape at the top. I hope the HOA doesn't notice...

I bent the one that came with my ductless air mini split. The only real difference is the factory one has an offset to hook up to the indoor unit. This one does not

Well packaged. Flares were well made, and insulation and outercovering were the best I've found.

Worked perfectly with unit.

was packed in a clear sealed bag and placed in a strong cardboard box and shipped quickly.Would certainly purchase this item again if needed.

Installation of a pre-charged mini-split.Was a bit unsatisfied with the product.Had to redo the flair fittings. They had folded over on themselves during the factory flaring process.
