Constant Torque Hose Clamps

This constant torque hose clamps describe a premium, heavy-duty hose clamp engineered for the most demanding applications. The name itself highlights its key features: a robust 15.8mm (5/8 inch) wide band, a constant tension spring mechanism, and the inclusion of washers on the housing for superior performance.

Material of constant torque hose clamps

W2 - Band and hosing SS301/304, screw galvanized steel, washer SS410.

W4 - Band, hosing and screw SS301/304, washer SS410.

Advantages of constant torque hose clamps

Maintains Seal Under Thermal Cycling: Perfect for modern engines with significant operating temperature swings.

Superior Vibration Resistance: The constant spring pressure and robust design prevent loosening caused by engine vibration.

Protects Hoses: The wide band and consistent pressure prevent hose damage, cutting, and cold flow deformation.

Heavy-Duty Reliability: Engineered for critical applications where failure is not an option.

Long Service Life: Made entirely from high-quality stainless steel, offering exceptional durability and corrosion resistance.

Constant Tension Design

This is the defining characteristic that sets this clamp apart.

Spring Mechanism: Unlike a rigid worm-drive clamp, this design incorporates a built-in spring in the housing that acts as a live, tensioning device.

Automatic Compensation: As the engine or equipment heats up and cools down, the hose and fitting materials expand and contract. The constant tension clamp automatically expands and contracts with them, maintaining a consistent, optimal clamping force throughout the entire thermal cycle.

Prevents Loosening: This dynamic action prevents the clamp from becoming either too loose (causing leaks) or too tight (which can damage the hose or bead) as temperatures change.

Common Applications of constant torque hose clamps

This clamp is a professional-grade component designed for high-stakes environments:

High-Performance & Racing Automotive: Ideal for turbocharger systems, intercooler pipes, coolant lines, and oil coolers where temperatures fluctuate wildly.

Heavy-Duty Trucks & Diesel Engines: Used in charge air systems, EGR coolers, and other high-vibration, high-temperature applications.

OEM Automotive Applications: Often specified by original equipment manufacturers for securing coolant hoses on the engine block and radiator.

Marine Engines: Where constant tension is needed to combat vibration and the corrosive saltwater environment.

Industrial Machinery: On equipment subject to intense vibration and thermal cycles.

In summary, the 15.8mm Band Width Constant Tension Clamp with Washers on the Housing is the superior choice for securing hoses in dynamic, high-stress environments. Its intelligent spring-loaded design, combined with its heavy-duty construction, ensures a reliable, long-lasting seal that adapts to its operating conditions, outperforming and outlasting standard worm-drive clamps.
