15.8mm Constant Tension Heavy Duty Hose Clamp

The constant-force hose clamp adjusts to pressure and temperature changes in the hose line. This prevents the clamp from loosening and leaks. The two-piece housing design allows for higher torques. The bushing prevents direct contact between the puncture hole and the hose, protecting it from damage during high-torque installations.

Constant tension hose clamps (also known as spring clamps or constant pressure clamps) are specialized hose clamps that maintain a constant clamping force even with temperature fluctuations or relaxation of the hose material. They are commonly used in automotive, industrial, and HVAC applications where a long-term, secure seal is required.
