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.

Constant-Tension Spring-Band Clamps for Firm Hose and Tube
These clamps have a wider band than other constant-tension clamps, which provides more coverage and reduces the chance of leaks.
The spring-action band lets the clamps automatically expand and contract with your hose or tube as temperatures fluctuate. Clamps are for firm plastic and rubber hose and tube.
Clamps with a zinc-plated finish resist corrosion in wet environments.
Note: When choosing a clamp, measure the outside diameter of your hose or tube with the fitting installed.
