About Measuring Hose and Tube Clamps
What's the best way to determine the clamp size you'll need? Simply measure the outside diameter of your hose with the fitting installed. Some clamps accommodate a range of sizes, so be sure the size you need falls in the middle of that range.

Tight-Seal Bolt Clamps for Soft Hose and Tube
The bolt design creates a 360° seal to prevent leaks. Clamps have rolled edges to protect hose and tube. They’re best for soft hose and tube but also work with firm hose and tube.
Galvanized steel and zinc-plated steel have fair corrosion resistance.
304 stainless steel and 300 series stainless steel have very good corrosion resistance.
Note: When choosing a clamp, measure the outside diameter of your hose or tube with the fitting installed.
