Pipe and tube clamps are essential for organizing and securing pipes and hoses in various systems. They simplify installation, ensure a clean layout, and help reduce vibration and noise. Clamps are specified by the "nominal pipe/tube size," which corresponds to the size of the pipe or tube they will hold, and the "bore," which is the diameter of the hole in the clamp insert. For accurate fitting, it's important to measure the outer diameter of tubes and the inner diameter of pipes before selecting a clamp.

Pipe is typically called out by inner diameter size and tube is typically measured by outer diameter size, so be sure to verify the OD of your pipe or tube prior to ordering. The "bore" is the the size of the hole in the insert that your clamp will come with. The "Nominal pipe/tube size" is the size of pipe or tube that will fit that particular clamp.
