The clamp is finished in a green metallic color and is suitable for general DIY, home and garden applications where a secure hose connection is needed.

Advantages

Its worm gear (screw) mechanism allows precise tightening to achieve a firm seal around hoses and pipes. Tool-free installation on pipe ends simplifies fitting, and the compact design fits standard hose diameters within the specified range.

How to use

Slide the clamp over the hose end, position the hose onto the pipe, then move the clamp so it sits evenly over the joint. Turn the screw mechanism clockwise until the clamp compresses the hose securely against the pipe. Check the connection under working pressure and tighten further if any leaks appear. To remove, loosen the screw counterclockwise until the clamp can be slid off.

Recommendations

Inspect the clamp periodically for corrosion or damage and replace if the screw mechanism becomes stiff or the band shows wear. Avoid over-tightening to prevent hose damage; tighten only until a secure, leak-free fit is achieved.
