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.

Plastic Worm-Drive Clamps for Firm Hose and Tube
Made of nylon, these clamps have excellent corrosion and chemical resistance, don’t conduct electricity, and weigh less than metal clamps. Worm-drive clamps are the most common type of clamp because they’re easy to use, strong, and versatile.
Clamps with a thumb head can be installed and removed using only your fingers.
Note: When choosing a clamp, measure the outside diameter of your hose or tube with the fitting installed.
