The Special Pierced Serrated Clamp is a customized worm drive clamp designed for applications with uneven hose geometry. Its unique feature is the precise piercing of special geometrical holes on the band to accommodate specific application requirements, making it suitable for hard hoses and complex setups.
The clamp operates on the worm gear principle. The gearing action between the serrations on the band and the thread of the Hex Head Screw allows tightening or loosening of the clamp. The serrations on both surfaces of the band provide a secure circular grip, preventing seepage.
● Designed as per German Standard DIN 3017-01 for precise customization. ● Includes special geometrical piercings tailored to fit uneven hose geometries. ● Serrations on the inner band surface enhance grip and prevent leakage. ● Available in a wide range of diameters with one-piece housing assembly for durability. ● Fully customizable to meet customer requirements.
