Anyone hard line there OBA lines?

I have had the York for quite a while installed where the battery goes with a tank in the back of the XJ. I've had regular air hoses ran but they are getting dry rotted and cracking from the heat and now leaking. I'd like to run copper tubbing and just hard line everything. Anyone have any comments on this good or bad? TIA Jeff CamoXJ

I'm getting ready to put OBA in soon. I'll be hard piping most of it using copper L-tube ACR, brazed with 15% sil-foss alloy rod. It's good for hundreds of psi, and easy to work with. There are many ways to terminate the ends using flares, mechanical joints, adapters, and vibration eliminators. Go to professional refrigeration-A/C supply house to see what's available.

I used 3/8" DOT nylon tubing throughout my OBA system. The stuff is used on big rigs for airbrakes (hence the DOT approval) is good for up to 300psi and is pretty flexible and you can get lots of different types of ends for it. I've used this stuff in airbag installs and it holds up well to high pressures and doesn't leak.

I just ran a cheapo line to the rear bumper (airtank) and used a bunch of zip-ties. I'm cheap, and it works, had it like that for over a year now. I only use my compressor when I'm actually using it though, I never have (compressed) air in the system unless I'm actually using it.

Forgive my ignorance, can normal brass flare fittings be used? Or does aluminum require diffrent stuff?

DOT line is about .60/ft ends vary by type but usually around a buck each.
