Wostore 50 Ft. Copper Pipes 1/4" & 3/8" for Mini Split Air Conditioner Insulated Coil Line Set Made in USA HVAC Refrigerant with Nuts

This was my first purchase of line sets for mini split air conditioners so I was leery of things like wall thickness, insulation durability and outside liner strength. I purchased 1/4 x 3/8" and 1/4 x 1/2" line sets and both worked great. The line sets were strong once in place, and not too difficult to bend while fitting into place. The outside covering stood up to all but the sharpest edges on my sanded holes in the steel walls (installed on a boat). I needed to soften the edges of the holes more. There has been no dripping or formation of sweat on the line sets (located in SE Fl) so insulation is doing its job. The wall thickness is approximately 28 thousands of an inch, and it has stood up to less than gentle handling. Wostore did a really nice job of designing and producing this quality product, and I have no hesitation using it instead of the more costly "name" brands.

Nice thick copper line set. This set was cut down to work on three different units. Pressure tested to 250#’s prior to vacuuming and charging. Couldn’t be happier.

Thicker copper. Insulation held up to light pulling. Would buy again

Overall use was, it did what was needed. The product performed as well as advertised. Will use again.

I used this for running a mini split and had to run the lines over some distance. They worked well and are running the mini split as I type this. I would recommend this product.
