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 Bolt Clamps for Firm Hose and Tube
The T-bolt design provides excellent strength and creates a 360° seal. Clamps have a spring that automatically adjusts the clamp diameter to compensate for the expansion and contraction of hose and tube when temperatures fluctuate. Clamps are for firm plastic and rubber hose and tube. Do not exceed the maximum torque or clamps may be damaged.
Zinc-plated steel has fair corrosion resistance.
301 stainless steel has very good corrosion resistance.
316 stainless steel offers excellent corrosion resistance.
Note: When choosing a clamp, measure the outside diameter of your hose or tube with the fitting installed.
