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.

Insulated Bend-and-Stay Metal Duct Hose for Air
- Very Flexible
- Compatible Clamps: Worm-Drive Clamps
- Color: Silver
- Temperature Range: -100° to 435° F
Bend this hose into position in heating and cooling applications where it’s important to maintain the temperature of the air inside the hose. Unlike fabric duct hose, this lightweight aluminum hose holds its shape once it’s curved around corners. It’s insulated with a layer of fiberglass, so it keeps air flowing through at a consistent temperature even when it’s routed through hot or cold spaces. The metalized film cover seals out moisture, protecting the insulation underneath.
This hose is not meant to be continuously flexed. Lengths beyond 6 ft. may need support.

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.
