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.

Super-Corrosion-Resistant Smooth-Band
Worm-Drive Clamps for Firm Hose and Tube
Made of our most corrosion resistant stainless steel, these worm-drive clamps stand up to harsh acids and chemicals. Their band is smooth and has rolled edges, so they won’t cut into your hose or tube. Worm-drive clamps are the most common type of clamp because they’re easy to use, strong, and versatile.
Note: When choosing a clamp, measure the outside diameter of your hose or tube with the fitting installed.
