Can aluminium lines with a single flare be used between the ****** and a cooler without worry? Is the al. strong enough? If it's not best to use, will steel with just a single flare work. I just want to double check before I start bending.
I'm ****ing with this on my daily driver now.Single flare 3/8" dia. steel lines are what was originally installed on my '95 GM.The original tubing has corroded and is leaking.I tried to subs***ute a double flared steel line today,into the OEM external cooler.The fitting on a 3/8" steel brake line is a perfect match for the original.But it didn't seal 100% the first try.I think the double flare isn't seating properly in a fitting designed for a single flare.If it still leaks tomorrow,I'll cut that end off and put a single flare on it.
Yes on both counts. You can use either aluminum or steel and the single flar with a worm type clamp should be fine.
