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.

Inspection and Measuring Fixturing

Use these components in coordinate measuring machine (CMM) applications to raise a workpiece and reliably position it on a fixture plate with ¼"-20 holes.

Spring and Plier Clamps

Spring Clamps

Squeeze the handles to open the clamp; release and the spring holds it tightly in place.

Extended-Reach Spring Clamps

The long, narrow jaws clamp farther into a workpiece and in tight spots.

Insulated Spring Clamps

These clamps meet DIN VDE 0680-1 for protection against accidental contact with live electrical circuits.

Miniature Spring Clamps

Clamp thin materials, or use in tight spaces.

Locking Miniature Spring Clamps

Press the lever to lock the clamp onto material.

Adjustable-Jaw Spring Clamps

Hold large workpieces with a standard-size clamp. Slide the jaws to adjust the opening size.

Spring Clamps with Telescoping Handle

Extend the handle to reach the clamp into tight spaces.

Spring Clamps with Flexible Arm

Attached to an arm you can flex into position, these clamps hold objects such as a flashlight, tool, or instructions.

Pliers-Activated Spring Clamp Sets

Set includes 12 clamps and the installation pliers required for positioning and removal.

Pliers-Activated Spring Clamps

Clamp thin sheet material together without drilling holes. These clamps open with special pliers and spring closed when the pliers are released.

Clothespins and Spring Clips

Hold lightweight objects, secure covers, and seal bags.

Spring Clamp Workholders

Secure small parts in spring clamps to keep hands free for soldering, gluing, and assembly.

Clamps for Hose, Tube and Duct Hose

Constant-Tension Spring-Band
Clamps for Firm Hose and Tube

These clamps have a wider band than other constant-tension clamps, which provides more coverage and reduces the chance of leaks.

Constant-Tension Spring
Clamps for Firm Hose and Tube

Not as bulky as our other constant-tension clamps, these round-wire clamps easily fit in cramped spaces. Use in low-pressure applications.

Constant-Tension Bolt Clamps for Firm Hose and Tube

The T-bolt design provides excellent strength and creates a 360° seal. Clamps have a spring that automatically adjusts the clamp diameter when temperatures fluctuate.

Constant-Tension Clamps for Soft Hose and Tube

Don't worry about your hose and tube expanding and contracting when temperatures fluctuate—these clamps have a Bellville spring that automatically increases and decreases the clamp's diameter.

Hose and Tube Clamp Pliers

Spring-Band Clamp Pliers

The tips adjust to accommodate the clamps often found on heater and radiator hoses.

Spring Clamp Pliers

Install and remove spring-tension hose clamps.

Stainless Steel Clips

Hold lightweight objects, secure covers, and seal bags in sanitary and corrosive environments.
