To eliminate "cold flow" leakage, you have to shut off the leak paths. Flex-Gear® heavy-duty constant tension clamps provide the self-adjusting band you need for a dependable seal, even in the coldest conditions.

Key features:

• Larger, heavier gauge, precision-formed spring washers provide higher rates of band tension and adjustment for a more dependable seal.    
• Inner liner prtects against shearing of hose surfaces.    
• Provides a uniform 360 degree seal.    
• Reusable.
