I dug out an old Airmaster Compressor the other day. It's about 15 years old and came from MM. The aluminium alloy pipe from the compressor to the receiver tank is badly corroded with a hole in it (had fertiliser granules of all things spilled on it). I've tried epoxy with no success. Spoke to MM but they can't identify the model from the ID plates on it, so no replacement pipe available. The compressor end has a compression fitting and the tank end has a flared fitting. Is there any reason why I shouldn't replace it with suitable diameter copper tube and compression fittings from a plumbing supplier?
