I have a chipper/shredder/vacuum that has a 10' by 6" spiral clear polyurethane hose for vacuuming flower beds, that has split about 1' from one end. I saw the receipt from the original owner, and this hose is expensive, and now, I see similar hose for about $18/foot. It obviously leaks, but with the spiral reinforcement, is still intact. I doubt duct tape will last long, but can a better repair be made? I do not see any products for this purpose, but can imagine it should glue well with some material.
