Re: suggested airline fittings when using aluminum hard line
I read somewhere that if you are trying to use softer line (like aluminum or nicopp) you need to use a tubing cutter to score the line where the teeth bite into it. I havent done it but the recommendation was to use regular line to get a mark and measure it to score the hardline.
I know there are special fittings for stainless hardline. Dont know if the can be used on aluminum though.
