Product Overview
Non-perforated Torro Worm Gear Hose Clamps

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.

  • Asymmetric Extension: Prevents the housing from tilting over when the clamp is tightened.
  • Safe Guidance: Screw support facilitates ease of assembly due to the safe guidance of the emerging band end.
  • Short Housing Saddle: Provides even contact pressure for reliable sealing.
  • Hose Protection: Smooth inside of the band offers optimal protection for all hose types.

Frequently Asked Questions
What materials are available for these hose clamps?
We provide W1 (zinc plated), W2 (partial stainless), W4 (304 stainless), and W5 (316 stainless steel) to meet various corrosion resistance requirements.
How does the non-perforated band protect the hose?
The non-perforated, smooth inside of the band prevents the hose from being cut or extruded through the band during tightening, extending the hose's lifespan.
Which material is best for marine environments?
For marine and salt-water applications, we recommend the W5 (316 stainless steel) material due to its maximum corrosion resistance.
What is the advantage of the asymmetric housing design?
The asymmetric housing ensures an even distribution of forces and prevents the housing from tilting over during assembly, resulting in a more secure connection.
Can these clamps handle high vibration?
Yes, the Torro design is specifically engineered for high mechanical loads and vibration, making it ideal for automotive and heavy industrial machinery.
What is the standard packaging for bulk orders?
Standard packaging involves products placed in plastic bags, then packed in sturdy boxes, and finally secured on pallets for safe international shipping.
