Product Description

Non-perforated Torro Worm Gear Hose Clamps (WNA)



Product Description

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.
The screw support facilitates ease of assembly due to the safe guidance of the emerging band end.
The short housing saddle provides even contact pressure.
The smooth inside of the band offers optimal hose protection.


Material, clamping range and your logo can be stamped on the band.
