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.
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.
