what are "Hardlines"

[steveo27]

Did a good bit of reading on here and have a general idea of what I want to do. However I have a few questions....

Basically, I want to do hard lines on a simple air setup. From compressor to water trap to tank, then from tank to VU4 manifold, and then from VU4 manifold to bulk heads.

1. Is it OK/smart to run stainless lines with brass compression fittings? I've seen a few set up with this combo and like the way it looks/contrasts. Will the brass ferrule in the fitting stick into the stainless hard line? Also, do I have to worry galvanic corrosion since they are 2 different materials? Or is it better to match the fittings and the lines?

2. Thoughts on Parker brass compression fittings?

3. What type of copper is typically used? Type L, type M, ect?

4. Is the anything special that needs to be done when installing hard lines into PTC fitting (like the lines between the bulkheads and the VU4 and the line from the tank to the VU4)?


I've done a few air ride installs before, but never with hard lines. So I have basic understanding of how everything works, but could use the help with the lines and fittings

1. No you should match the same materials. Stainless is much harder then copper and requires "stronger" fittings.

2. Parker's products are all very good.

3. Type L

4. Be sure to make all your cuts perfectly straight, measure twice and cut once. Take your time!

Any information on how people do the brass fittings with the stainless? Would using a stainless ferrule in the compression fitting bite into the stainless hard line or would it just cause the fitting to expend and become junk?

people use aluminum line with brass fittings, not stainless. also you cannot use stainless line with PTC fittings unless the PTC fitting is specifically made for stainless which is incredibly rare

finished up Cloudvi's setup this week. color matched the top tank matte white to match the wheels, and polished the lower, accuair exo mounts and alot of copper later= finished product

[Bazmcc]

Nice work.

What sort of bulkhead fittings have you used there?

ive used Parker fittings on just about every set up ive done, havent had any problems with them so i havent othered using any other brand

just had mine done yesterday/today a friend did it for no charge. i just wanted a clean simple design that still allowed for some trunk room in the small cabrio trunk area.



and here's the new intake. coolant line is now under the intake tube

what is easier, powercoated or painted lines? i still planning my system with a friend but we are think about both ways..

Powder would probably be easier...less prep/post work than paint, and it tends to be a bit of a more resilient finish than paint as well.

Even more stunning in person pics do no justice thanks, Greg, you are truly talented at what you do

Some hardlines I did for a friend the other day. 3/8" aluminum, black AN fittings with brass bulkheads.

Did some copper lines yesterday, on the setup yesterday. Not sure if I'm going to stick with them though. Quick question, for those doing stainless lines (or aluminum?), what fittings have you found are the best? Here's a pic of the copper lines, vibrates against the tank though, so not keeping it.

Clean and simple

Are any of you guys using stainless tubing with ISO Bubble flares? I usually use 37º single flares (AN/JIC), but I'm interested in doing some brake lines in Stainless. I'm not sure if my OTC Stinger bubble flaring tool will be up to the job?

jw how dose that work with the lines coming from one false floor to the other? unless its just hard to tell in the picture. it just seams like an accident that was covered up to me.

Wow, I want this. FS?

Hi Guys, amazing hardlines!

Questions for people who using hardlines on your ACCU VU4,

Did you get any leaking on those PTC ports?

Some small leaking on my system, any idear? I use steel hardlines & Bite type fittings

Did some work with some wiring and 1/2" lines today.
