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 Clamps for Firm Hose and Tube
Single Spring
Double Spring
Not as bulky as our other constant-tension clamps, these round-wire clamps easily fit in cramped spaces. Use in low-pressure applications.
Clamps automatically expand and contract with your hose or tube in response to fluctuations in temperature. They are for firm plastic and rubber hose and tube.
For single spring clamps, use the optional spring clamp pliers to install and remove the clamps.
Double spring clamps spread the clamping force more evenly around a hose or tube than single spring clamps. However, the clamping force is lower than the single spring clamps. To install and remove the clamps, use optional straight-nose pliers.
Zinc-plated steel clamps have fair corrosion resistance.
17-7 PH stainless steel clamps have good corrosion resistance. They are heat treated, so they are stronger than steel to better retain their hold.
Note: When choosing a clamp, measure the outside diameter of your hose or tube without the fitting installed.
