## Description

Why choose us?Insulated copper line set for use with ductless mini- split systems. Linesets compatible with all manufactures, Mitsubishi, LG, Fijitstu, Daiken etc...Pure copper pipeSeamless copper tube showing no leaks, high and low pressure lines.Thickened insulated cottonThe insulated cotton is thick and solid with fireproofing and flame-retarded function, by which the burning stops immediately upon leaving the flame and only the outer layer of the cotton turns into power.

Review: 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.
Review: 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.
