you can run 116 octane race gas and methanol thru aluminum parts without hurting the aluminum at all. People change SS parts to aluminum for weight savings on race cars all the time. I can't see where butane would effect aluminum. But I'm no expert(fur shure:banana1sv6:) and have never used aluminum.
yeah i'm with ya buddy but i know some materials you are not supposed to use for bho as it can leech into the bho.
drgreengenes thanks for the link! i think i'm ordering one of these it's easier at that price to just buy one then wasting time sourcing all the part to save a few bucks.
If you look at the prices, they are much lower on ebay, especially for the XL extractor (79 vs 200). Got me interested, I have lots of materials ro blast...
