14.2 mm Constant Torque Hose Clamp
The DISLAB PRECISION 14.2 mm constant torque hose clamp combines worm-drive adjustment with an elastic Belleville spring compensation system. It helps maintain consistent clamping force as a hose expands, contracts or relaxes during temperature changes, vibration and repeated operating cycles.

Why Use a Constant Torque Hose Clamp?
Conventional worm-drive clamps are tightened to a fixed position. When a hose becomes softer, contracts in cold conditions or relaxes after repeated heating cycles, the original clamping load may decrease. This can create a path for coolant, air, oil or process fluid to escape.
A constant torque hose clamp adds a spring-compensation mechanism to the adjustable worm-drive structure. The spring pack continues to apply controlled tension as the joint changes, helping the clamp follow the hose instead of remaining completely rigid.
- Helps compensate for thermal expansion and cold contraction.
- Supports more consistent sealing under vibration and pressure variation.
- Reduces direct contact between band perforations and the hose surface.
- Provides adjustable installation through a familiar worm-drive mechanism.
What Problems Does This Clamp Help Solve?
This design is intended for hose joints where a standard fixed-tension clamp may lose effective sealing force as operating conditions change.
Thermal Expansion and Contraction
The Belleville spring pack can flex with dimensional changes in the hose connection, helping preserve clamping pressure through repeated heating and cooling cycles.
Vibration-Related Sealing Loss
On engines, trucks and heavy machinery, continuous vibration can affect rigid connections. The spring-compensated structure supports a more stable load on the hose joint.
Damage to Soft Hose Surfaces
The inner liner covers the perforated band area, reducing direct contact between the serrations and silicone, rubber or other flexible hose materials.
Frequent Retightening
By compensating for hose relaxation, the clamp can reduce the need for repeated manual adjustment in suitable applications and properly engineered joints.
How the Constant-Torque Structure Works
The clamp is tightened through the worm-drive screw in the same general manner as an adjustable hose clamp. The difference is the spring assembly positioned around the screw section. When the hose joint changes in diameter, the spring stack can deflect and continue transferring load into the band.
Key Construction Features
Spring-Compensated Tension
The spring assembly helps maintain load as temperature, vibration and hose relaxation affect the connection.
Smooth Inner Liner
The liner separates the hose from the perforated band, helping reduce cutting, pinching and surface marking.
Rounded Band Edges
Formed band edges help prevent sharp metal contact with rubber, silicone and reinforced flexible hoses.
Precision Worm Drive
The M8 screw and formed housing provide practical adjustment during assembly, maintenance and hose replacement.

Where Constant Torque Hose Clamps Are Used
The clamp is suited to hose connections exposed to heat, vibration, pressure changes or long operating cycles. Final selection should be based on hose construction, working temperature, fluid type and joint design.

Frequently Asked Questions
Practical information for selecting and sourcing constant-torque clamps for industrial hose assemblies.
What does “14.2 mm” refer to?
It refers to the nominal band width of the clamp. The source specification also lists a 15.8 × 0.8 mm band configuration, so the required band size should be confirmed when requesting a quotation.
How does the clamp maintain more consistent tension?
A Belleville spring stack is installed around the screw assembly. The spring can deflect as the hose joint expands, contracts or relaxes, helping the band continue applying clamping load.
Can it be used on silicone turbo hoses?
It can be considered for silicone turbo and intercooler hoses when the clamp diameter, band width, temperature rating and required clamping force are suitable for the hose and fitting.
What is the purpose of the inner liner?
The liner covers the perforated portion of the band so the hose surface is not pressed directly into the band serrations. This helps reduce cutting, extrusion and surface marking.
What is the difference between W2 and W4?
In the listed W2 configuration, the band and housing are stainless steel while the screw is galvanized steel. In the listed W4 configuration, the screw is also stainless steel. Confirm the exact component grade before ordering.
What information is needed for a quotation?
Provide the hose outside diameter, required adjustment range, band width, material class, operating temperature, fluid type, application, order quantity and packaging requirements.
