Band clamp with a worm drive equipped with a spring for compensating dimensional changes in the connection (shrinkage of the hose due to cold flow of the material or due to large temperature variations). The spring consists of a set of 8 disc springs (washer springs) – washers under the head of the screw. This ensures the retention of the clamp’s grip and sealing around the entire circumference of the hose, preventing leaks from the installation. The spring mechanism of the clamp allows for automatic adjustment of its diameter while maintaining the clamp’s grip. Particularly recommended in cases of large temperature changes. Proper clamping of the clamp is indicated by the screw end protruding beyond the housing of the lock and the flattened disc springs. The internal insert of the clamp protects the hose surface from damage. Installation tightening torque 5.6 Nm (max. 9.6 Nm). Screw/lock material: stainless steel 410. Band material: stainless steel 300. Band width: 14.3 mm (9/16″).
