Q: What size and type of clamp should be used?
A: To obtain uniform compression around the tube or hose, we recommend the use of a stepless ear-type clamp as we have on this site. The clamp must be sized so that it will still slide over the tube after the barbed fitting is inserted, and exert sufficient compression on the materials before the clamp is fully closed. When soft materials are involved, it must be recognized that the clamp will sink into the materials somewhat, perhaps necessitating a smaller sized clamp. When properly sized, the sides of the ear should not be touching each other when the clamp is installed
