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 Twin-Ring Bolt Clamps for Firm Hose
A double ring of thick wire provides a complete seal around large-diameter hose.
Clamps are zinc-plated steel, which has fair corrosion resistance. They are for firm plastic and rubber hose. Do not exceed the maximum torque or clamps may be damaged.
Note: When choosing a clamp, measure the outside diameter of your hose with the fitting installed.
