I recently installed an LG mini-split heat pump (purchased from SupplyHouse) for a customer, and this was the line set I used. NO PROBLEMS!

I woul;d not repurchase
What discovered was if you use this line as is you are fine, if you have to cut and re flare this line you are going to have trouble. The line description does not match the US Engineering Data Specifications for refrigerant copper line, as such no one the correct size adapters to fit this line because of the non standard specifications: See for yourself:
HVAC Copper dimensions Imperial:
1/4 copper OD is .250, ID is .190 wall thickness is .030
3/8 copper OD is .375, ID is .311 wall thickness is .032

Closest 1/4 metric dimensions are
OD is 6.35mm, ID is .483mm wall thickness is .76mm
Closest 3/8 metric dimensions are
OD is 9.53mm, ID is .791mm wall thickness is .81m

Pine holes in 1/4 line after 3 years
Installed this 3 years ago and now the 1/4 line has pin hole leaks along a 6 foot section of it. I have seen other reviews with the same issue, hopefully this was just a bad batch made 3 years ago.

Warning
Pinhole Leaks Occured Aftet Three Years In Service. Extremly Costly To Diagnose, Repair And Replace.

Warning
3 1/2 years into my systems operation line set had failed. Pinhole leaks occurred in copper causing refrigerant leak. Looking into situation.
Possible chemical reaction caused by white insulation and condensation. Extremely expensive FIX. I am a HVAC Mechanic. I feel very sorry for home owners or business owners that have to go through this. Can't even begin to imagine the bill for somebody to hire a HVAC company to diagnose and repair this disaster.

Perfect line set for Daikin
I searched all over for (2) 100 ft line sets for a Diakin 2 head mini split. These worked great. They are sturdy and well insulated. I had to cut them to length and flare them. Nice and easy to flare (use the correct tool!). They sealed perfectly and they worked great.

Avoid at all costs
The 7/8" lineset is nearly useless. To start with, it shipped in the original box without any protection inside of it. The box had so much damage, it's hard to believe it was all from shipping. The lineset insulation was split in multiple spots from being tossed around. Next, the copper tube itself is poorly made and isn't round enough to slide into a fitting without reshaping it. This oval shape also makes it difficult to cut with a pipe cutter. Stick with the name brands; you'll end up spending more on labor with this.

Betty split line said great price excellent delivery
Haven't installed the line set yet, so I'm hoping the flares will be good. The fittings will go on snuggly. Price was half that of a line set from the manufacturer and delivery was excellent.
