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.

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.

Duct Hose Clamps for Spiral Duct
Also known as bridge clamps, these worm-drive clamps align with the spiral support on wire duct hose to provide a tight seal.
When looking at the end of your hose, a right-hand spiral twists away from you clockwise; a left-hand spiral twists away from you counterclockwise. Clamps have very good corrosion resistance. 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.

Duct Hose Clamps with Grounding Cable
Prevent static charge buildup while securely connecting duct hose with a wire spiral. These clamps come with a grounding cable to protect you and your equipment from shock, even in dusty areas. Because the cable connects through the bridge of the clamp, you can ground your hose without damaging it or exposing the spiral.
To create a tight seal, these clamps—also known as bridge clamps—align on both sides of the wire spiral in your duct hose. The bridge crosses over the top of the wire to hold the clamp in place. Made of stainless steel, these clamps also resist rusting.
All of these clamps are for right-hand spiral hose. When looking at the end of your hose, a right-hand spiral twists away from you clockwise. To choose a clamp, measure the outside diameter of your hose with the fitting installed. Do not exceed the maximum torque or you may damage your clamp.
