In making high vacuum systems in our physics lab at UT Austin, the students using them made of all stainless steel with metal gaskets. Then they would wrap heating tape around all the pipes, start their pumps and bake the system at 400 deg.C to get rid of all of the moisture and other corruptions. Then they could get vacuums of 10^-11 to 10^-13. Purging with a dry gas is a better substitute for car AC systems.
