I want teflon crimped stuff. Best temp and psi properties..
Been trying to make things as safe as possible on my car... the breather puke tank, coolant puke tank, and trans puke tank are all mounted in the trunk of car behind the tires. I run a belly pan under the engine... just one last thing to be safe about. Temps get pretty warm on the tbrake building boost.
teflon is good to 450 degrees and not that its needed but crimp fittings hold 1000 + psi
