question about hard air line

What kind of copper do i need for hard air line? Is it the refrigeration line, or specifically for air line? Where can i get it? Lowes, Home Depot, where? Please help.

acklands sells it...I believe it is L type... but don't qoute me, and there are gonna be tonnes of people who tell you copper is no good blah blah blah... dont listen to them, I ran it on my daily for 3 years, snow, rain, summer.... never had a problem at all.

what is acklands? Is L type for air or refrigeration or what? Also, do i use regular push to connect fittings for it? Thanks for the help, by the way.

I got mine from my local auto parts store. I don't think the refrigeration is the same. The presure raiting on mine was around 700 psi. I believe acklands is only in canada. I am using compresion fitings so did aaron. But you could also use flare fittings. Not sure on push connect.

refrigeration copper is sold by outside diameter such as 3/8ref 5/8ref etc. tyle L is a pluming standard such as m, or k. most common is 3/8L wich is 1/2od. that is what i sell ekstensive metal works in houston tx. i hope this helps. make sure you use a tube bender.

Yea i used the spring benders on mine ,,and i have push fittings on mine as well,,they are legris fittings ,,,been done sense 03 with knock on wood no trouble

Use copper line at your own risk. I know a lot of people have used it with great results, but that doesn't make it right-
Just look at the "reverse 4 link" thread for THAT argument!
Copper, when used in an environment where vibration is present, WILL work-harden. This means that the road vibrations and shock from dragging and hitting bumps will make copper line brittle over time...
You can get mild steel line for around the same price as copper, and stainless for a bit (OK, a LOT) more, so just do it right the first time!

With flare, make sure you get matching pitch angle, with the tube nut and flare fitting.

ill say coppers okay i watched my friend accord flip three times and while flying over a lake then land directly on the tires when he totalled the car the only thing left in working condition was the air system which was all plumbed with copper line he was litteraly sitting at full lock with the roof smashed into the seats it was crazy

i got copper on mine with ptc, and every once in a while one will blow out, and i replace it with compression, and have never had a problem with em, just make sure you don't over tighten em
