The worm drive hose clamp with wave spring according to DIN 3017 is a multi-range hose clamp that is ideal for applications with high mechanical loads and large temperature fluctuations.
A corrugated spring is fitted on the inside of the band of the standard hose clamp, which means that sufficient clamping force is still achieved even at extremely low temperatures or extreme temperature fluctuations.
Our premium product is the NORMACLAMP® TORRO® WF worm drive hose clamp with wave spring.
The main feature is its asymmetrical housing and the wave spring. The inside of the band is smooth or embossed for optimum hose protection.
