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.

Slotted, External Hex Drive Style

Slotted Drive Style

A raised safety collar around the head of the screw prevents your screwdriver from slipping and damaging the hose or tube. Clamps are for firm plastic and rubber hose and tube. Do not exceed the maximum torque or clamps may be damaged.

201 stainless steel clamps have a zinc-plated steel screw and offer good corrosion resistance.

301 stainless steel clamps resist corrosion better than 201 stainless steel clamps. All have a 410 stainless steel screw.

Note: When choosing a clamp, measure the outside diameter of your hose or tube with the fitting installed.
