Yellow zinc spiral clamp

Heavy-Duty Spiral & Bridge Hose Clamps

Our Spiral Hose Clamps (also known as Bridge Clamps) are the engineered solution for securing hoses with external helix reinforcements. Standard flat-band clamps often leave gaps when crossing over the spiral wire of a corrugated hose. Our specialized "Bridge" design steps over the reinforcement, providing a continuous, uniform seal that prevents air and fluid leaks.

It is a specialized clamp designed for use with helix/convoluted hoses, available in both clockwise (right-hand) and counter-clockwise (left-hand) orientations to match the hose's convolution direction. The clamp fits between the hose's helical ribs, securely gripping the full circumference of the outer wall rather than the convolutions, ensuring a safe, economical, and efficient securing method. Its spiral design aligns with the hose's convolution direction, and proper orientation should be confirmed with the hose manufacturer.

Material:

W1 - all parts carbon steel with zinc plate

Key Features:

• Integrated Bridge Technology: The offset bridge fits perfectly over the hose's spiral wire, ensuring tight contact with the hose surface.

• High-Grade Materials: Available in AISI 304/316 Stainless Steel for corrosion resistance in harsh industrial or outdoor environments.

• Precision Tensioning: Equipped with a robust worm gear mechanism that allows for high tightening torque without slipping.

• Clockwise & Counter-Clockwise Options: We supply both Right-Hand (RH) and Left-Hand (LH) versions to match the winding direction of your specific spiral hose.

• Hose Surface Protection: Rounded band edges prevent cutting or abrading the hose material during high-pressure applications.

Applications:

• Woodworking: Dust collection systems and vacuum extraction lines.

• Industrial: Material handling for plastic pellets, grain, and powder.

• Agriculture: Suction and discharge hoses for irrigation and pumping.

• HVAC: Flexible ventilation ducting and spiral air hoses.

FAQ

Q1: How do I know if I need a Clockwise (RH) or Counter-Clockwise (LH) spiral clamp?

A: Look at the end of your hose. If the spiral wire winds away from you in a clockwise direction, you need a Right-Hand (Clockwise) clamp. Matching the direction is crucial for a proper seal.

Q2: Can these clamps be used on standard smooth hoses?

A: While they will function, the bridge is specifically designed for spiral reinforcements. For smooth hoses, our standard Worm Drive or T-Bolt clamps provide a more efficient and flush seal.

Q3: Are these clamps suitable for high-vibration environments?

A: Yes. The bridge design combined with a high-torque worm gear ensures the clamp stays secure even in high-vibration dust extraction or industrial pumping systems.
