15.8mm Constant Tension Heavy Duty Hose Clamp

The Constant Tension Hose Clamps is built to adjust for changes in pressure and temperature in the hose line. This stops the clamps from getting loose on the hose and prevents leaks. 2 pieces housing design is suitable for higher torque. The liner prevents direct contact of perforations with hose, protect the hose won’t get damaged when install with high torque.

Constant Tension Hose Clamps (also known as spring clamps or constant-pressure clamps) are specialized hose clamps designed to maintain a consistent clamping force over time, even under temperature fluctuations or hose material relaxation. They are commonly used in automotive, industrial, and HVAC applications where a secure, long-term seal is required.
