Heavy duty hose clamps, also referred to as hose clips, were created to form the best seal between a hose and whatever you are connecting it to, often called the barb or the nipple. Think about the bunsen burner hose you connected at the lab table in science class many years ago. Remember how it fit on the cone-shaped gas line? That would be considered a barb. In science class we just put the hose on, did our little experiment, and we were done, but if you needed to fix something permanently, you would use a hose clamp over the hose to create a tight fit.
Now that we know what a heavy duty hose clamp is, what else can we learn about them? Clamps come in a wide variety of sizes but are typically used for hoses that are at least a half inch in diameter. If you don’t use the right size, you can get a
