A double ring of thick wire provides a complete seal around large-diameter hose.

Clamps offer extra holding power in high-torque applications.

A thumb screw instead of a slotted screw allows you to install these clamps without any tools.

Here's everything you need to make your own 3" diameter and larger custom-length worm-drive clamps.

Made of our most corrosion resistant stainless steel, these worm-drive clamps stand up to harsh acids and chemicals. Their band is smooth and has rolled edges, so they won’t cut into your hose or tube.

Unlike vibration-resistant pinch clamps, these have a torque rating for extra holding power in high-vibration applications. They are also known as high-torque clamps.

Twist the thumb head with your fingers to tighten these clamps. Once tightened, remove the thumb head to minimize your clamp’s profile and make it harder to tamper with.

Use to tighten low-profile band clamps, then break off the excess banding.

Also known as bridge clamps, these worm-drive clamps align with the spiral support on wire duct hose to provide a tight seal.

The bolt design provides high strength and creates a 360° seal to prevent leaks.

Remove the bolt and flip open the hinged bridge to install.

Clamps come packed in a box with individual compartments for each clamp size. To make sure they won’t cut into hose and tube, they have a smooth band with rolled edges.

Create 4" diameter and larger worm-drive clamps that withstand high-temperature applications.

Clamp down on nonreinforced hose and tube to squeeze it shut, eliminating the need to drain the hose when working on pumps, heating and cooling systems, and fuel lines.
