Germany type bridge clamp

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

These clamps maintain 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 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.

Application:

Engineered specifically for optimal performance with spiral-wound ducting, bridge clamps are 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
