Product Description
Torro Worm Gear Hose Clamp

Torro Worm gear hose clamps are especially suited to applications with high mechanical loads. The improved asymmetric housing ensures an even distribution of forces and safe assembly. The asymmetric extension prevents the housing from tilting over when the clamp is tightened.

  • Safe Guidance: The screw support facilitates ease of assembly due to the safe guidance of the emerging band end.
  • Even Pressure: The short housing saddle provides even contact pressure.
  • Hose Protection: The smooth inside of the band offers optimal hose protection.
  • Customization: Material, clamping range and logo can be stamped on the band.

Frequently Asked Questions
1. What makes "Non-Perforated" clamps better for hoses? The non-perforated band features a smooth underside which prevents the hose from being cut or sheared during tightening, ensuring a longer lifespan for the connection.
2. How does the asymmetric housing improve safety? The asymmetric design provides an even distribution of forces and prevents the housing from tilting or shifting when high torque is applied, ensuring a secure seal.
3. Which material should I choose for marine applications? For marine or salt-water environments, we recommend the W5 (316 Stainless Steel) material code as it provides maximum corrosion resistance.
4. Can I customize the clamps with my own branding? Yes, we support OEM/ODM services. We can stamp your logo, specific materials, or custom clamping ranges directly onto the band.
5. What is the difference between W2 and W4 materials? W2 uses a zinc-plated screw with a stainless steel band and housing. W4 features 100% stainless steel for the screw, housing, and band, offering higher corrosion resistance.
6. What is the typical lead time for large orders? With a monthly capacity of over 1 million pieces and automated production lines, we ensure fast delivery and stable supply for large-scale industrial and OEM projects.
