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.

Worm-Drive Clamps with Smooth Bands for Soft Hose and Tube
Clamps have a smooth band with rolled edges to prevent them from cutting into your hose or tube. They’re best for soft hose and tube but also work with firm hose and tube. Do not exceed the maximum torque or clamps may be damaged. They all meet either DIN or SAE dimensional standards. Some are ASTM rated for titanium composition.
Zinc-plated steel has fair corrosion resistance.
430 stainless steel has good corrosion resistance.
304 stainless steel has very good corrosion resistance.
PTFE-coated titanium is more corrosion resistant than stainless steel, making it the best choice for applications involving harsh acids and chemicals. It’s also stronger than stainless steel, yet still lightweight. It has a natural slippery surface, which reduces friction and prevents clamps from damaging hose or tubes.
Note: When choosing a clamp, measure the outside diameter of your hose or tube 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.
