Is the problem at the bottom end? Th ppe should be able to movein the bottom casting. It needs to be abe to move in and out freely, as well the pipe needds to be able to rotate somewhat on the ball end of the pipe. If this is not the case, the pipe will break, or worse, something else will. I think a small amout of clearance was part of the design as the fan would clear any gas leakage. The designers weren't as pc back then. I too want these pipes to work
