| What I do is use a piece of the Aerotrend that fits the outlet snugly, and is about 1/2" wide, cut even with the end of the metal outlet to create a rubber collar on teh outlet tip. THEN I go up a size of tubing for the extension so it fits over the "collar" of the other shorter piece. That eliminates any chance of back pressure.
