You can save some weight and money by using standard "Tie Wraps" (Cable Ties in the AC Spruce catalog) for your cold air SCAT tubing clamps. Spruce carries a version ("Cobra Clamps") that lies flat if you need it to look nicer and can't hide the connector.
For the Hot air connections; the Aviation Dept of your local Auto Parts store carries "Constant Velocity Boot Clamps", which are essentially 1/4" wide Stainless Steel Tie Wraps. I've seen two versions of the clamps; the cheaper version ($1.25) you simply pulled tight and then pulled it 180 degrees in the other direction and bent down two tabs; clipped the excess and were good to go. The other (@ 2.20 ea) used metal 'teeth' in slots and the a final squeeze on a tension tab with my nippers (but not tight enough to cut the metal).
Both work very well and weigh about 1/4 oz. vs nearly a full oz. for a standard screw clamp. With ten clamps in my total system system, using the plastic and metal tie wraps saved about 1/2 lb and a couple of bucks - with no extra work.
