China Suppliers Factory German-Type Stainless Steel Hose Clamps (DIN 301for Automotive, Plumbing & Industrial Use
Key Features & Benefits
Eliminates sharp edges and holes that can cut or tear hoses, extending the service life of rubber and plastic tubing.
Trapezoidal worm teeth provide smoother torque transfer, better self-locking, and consistent clamping force even under vibration or thermal cycling, preventing loosening.
Available in premium 304/316 stainless steel (W4 grade) or galvanized steel options, suitable for water, oil, gas, and mild chemical environments.
Wide adjustment range accommodates common hose and pipe diameters, reducing inventory complexity for multi-size projects.
Fits rubber hoses, PVC pipes, fuel lines, coolant hoses, and more in automotive, plumbing, HVAC, and marine systems.
Cross-recessed screw head works with standard screwdrivers or power tools for fast, secure installation.
