Our SY-117 Stepless 1-Ear clamp is simple to install, the installing work is very fast, not matter what type of hose it is, and the most important thing is to select the correct size. Customer can check the maximum size on our product which is stamped into the clamp itself, and a general rule is about a 2.5mm range for each clamp. For example, a clamp that is stamped “13.3”, it means the approximate range from about 10.8mm to 13.3mm. The clamp is one piece, so you have to remove the hose to slide the clamp over the hose, and then push back the hose.
