Line set 50FT 1/4" & 3/8"

The price is good! But you get what you pay for! Very thin walled line set. I went to torque the connector and it twisted like a pretzel! Also not thick enough to put tight bends on it without kinking! Don't buy and save yourself a lot of aggravation!

The exterior diameter a little smaller than 1/4 not easy to flare perfect if you don’t cut the length

INACCURATE PRODUCT DESCRIPTION! THIS IS NOT 1/2" x 1'4" tubing it is MADE IN CHINA so METRIC...Probably OK if you do not need to shorten and find the factory flares to be good. Trying to re-flare difficult unless you have a metric flaring tool. CLEARLY MARKED ON INSULATION THAT copper lines are 12mm (.472 inch) x 6mm (.236 inch) so slightly smaller than 1/2" x 1/4".

Copper gauge is a lot thinner, I had trouble making the flare connections. Luckily, I had sand paper to make the tubing lock on the flaring tool. The older copper tubing fits the flaring tool perfectly!My first time installing my own mini-split.

First of all it’s thin copper and you can tell by the weight. So thin in fact I could not even flare the 1/4” tube with my yellow jacket premium flaring tool. It’s smaller than the 1/4” hole and pushes through—Just so frustrating it’s not worth it and your paying less for less copper anyway.

I doubt this meets any ASHRAE spec, copper wall thickness probably 60% of spec linesets (even those shipped with Senville gear). I was able to use it to extend regular linesets with a legit braze joint, only once (of 8) cooked through the thin wall, had to redo. Time will tell if this alloy holds up electrochemically...

Had to shorten the line set and re flare. The diameter of the 1/2” line was smaller than the flare tool. The flare tool would push it through the flare clamp. It appears to be off about 1/64”. Typical Chinese product

1/4" pipe is less than 1/4" and its extremely thin walled. Had to add tape to get it to hold in flaring tool
