Heavy-Duty Bridge Hose Clamps for Spiral Hoses

Our Bridge Hose Clamps are the professional sealing solution for hoses with external helix reinforcements. Unlike standard clamps that leave gaps over the spiral wire, the integrated "bridge" design steps over the reinforcement to provide a complete, airtight 360-degree seal.

Description:

Bridge Clamp is engineered to securely fasten over the helical ribbing of wire-reinforced ducting, ensuring a leak-proof seal by precisely aligning with the hose's spiral structure. Their reinforced bridge design enhances clamping force distribution, preventing slippage even under high pressure or vibration.

While functionally similar to standard worm-drive clamps, bridge clamps distinguish themselves through:

 - Heavy-duty construction (wider band, hex-drive screw) for superior torque resistance

 - Optimized grip on corrugated/spiral hoses by conforming to the helix pattern

 - Enhanced sealing performance in demanding HVAC, industrial, and automotive applications

The bridge hose clamp maintains their classification as worm-gear clamps, but represent the high-performance tier of this fastener family. Their specialized design makes them ideal for critical connections where standard clamps might fail. 

Material: 

W2 - Hosing, band and bridge stainless steel 201/301/304, screw carbon steel with zinc plated

W4 - All parts stainless steel 201/301/304

Features:

Bridge Clamp is available in both clockwise (right-hand) and counterclockwise (left-hand) spiral variants to match different hose configurations.

How to Determine Spiral Direction:

When viewing the hose end-on:

A right-hand (clockwise) spiral appears to twist away from you in a clockwise direction.

A left-hand (counterclockwise) spiral twists away from you counterclockwise.

Industry Standard:

Most hoses follow a right-hand (clockwise) spiral pattern, making clockwise clamps the more commonly used option. However, specialized applications (such as certain industrial or automotive systems) may require left-hand variants.

Dimension chart: 

The bridge hose clamp is manufactured in a comprehensive size range from 2 inches (50mm) to 20 inches (500mm) in diameter, accommodating virtually all industrial and commercial ducting applications. Each size is offered in both right-hand (clockwise) spiral configuration and left-hand (counterclockwise) spiral configuration.

Advantage:

• Integrated Bridge Design: Specifically engineered to fit over the spiral wire of corrugated hoses, ensuring uniform pressure.

• High-Grade Materials: Manufactured in AISI 304/316 Stainless Steel or Zinc-Plated Carbon Steel for superior corrosion resistance.

• Precision Tensioning: Robust worm gear mechanism allows for high tightening torque without slipping.

• Safety Edges: Rounded band edges protect your hose from cuts or abrasions during high-pressure applications.

• Directional Options: Available in both Clockwise (Right-Hand) and Counter-Clockwise (Left-Hand) versions to match your specific hose spiral.

Application:

Engineered specifically for optimal performance with spiral-wound ducting, the bridge hose clamp is the professional's choice for creating reliable, leak-proof connections. These heavy-duty fasteners feature a unique design that perfectly conforms to the helical ribbing of wire-reinforced hoses, ensuring maximum contact and sealing efficiency. They are widely used such as:

HVAC systems - for secure spiral duct connections

Industrial ventilation - in dust collection and fume extraction systems

Engine compartments - where vibration resistance is critical

Process piping - for chemical and air handling systems
