German Type Hose Clamp

Availability:
German hose clamps are widely used worm-drive hose clamps for automotive and industrial piping systems. They feature a non-perforated band design, providing uniform clamping force distribution and stable locking performance, ensuring reliable sealing under vibration and pressure fluctuation conditions.

Why choose Yueding?
  • Certified under ISO and IATF systems, ensuring consistent automated production across different batches of hose clamps over long-term supply.
  • Standard inventory coverage from 16–50mm, supporting bulk purchasing and mixed-size order requirements.
  • Integrated supply capability covering design, manufacturing, and packaging, with structural customization available based on specific application requirements.

High Consistency Production Compliance

Our German hose clamps are manufactured in accordance with DIN 3017-1 standard, ensuring interchangeability in both size and structure. This helps reduce replacement and compatibility risks between different suppliers, and makes it easier for unified use in OEM and distribution systems.

Supported by a highly automated production system, our daily output can reach up to 1.5 million pieces. For large-diameter German hose clamps, semi-automatic production with manual support is used to adapt to structural variations and size range requirements, while maintaining stable tolerances in band width and thickness, ensuring reliable assembly performance for your applications.
