DIN 3017-1 Hose Clamp Germany Type Asymmetrical Lock
Le Collier de serrage de type Allemagne with Asymmetrical Lock is a worm drive hose clamp manufactured to DIN 3017-1 (Type A / Type B). Its defining feature is an off-center (asymmetrical) band design that distributes clamping force more evenly under high torque, preventing deformation during installation — unlike symmetrical German middle-type clamps.
🔧 Structural Feature
Band Design: Asymmetrical / Off-center
Edge Treatment: Edge pressing design (protects hose surface)
Connection Method: Point welding (band to housing)
⚙️ Mechanical Advantage
Higher load torque than symmetrical German middle type
Uniform force distribution prevents band twist/deformation
Suitable for high-torque installation scenarios
🎯 Typical Applications
Automobile engine connections
High-vibration industrial equipment
Heavy-duty commercial vehicles
Turbocharger intake/exhaust hoses
