Junior Clamps

Hydromet Junior Clamps are designed for repairing leaks and damaged sections on smaller-diameter pipes. The clamp wraps fully around the pipe to provide a full-circumference seal and is manufactured to suit specific pipe materials, including galvanised steel, copper and polyethylene (PE).

Available in 75 mm and 150 mm lengths, Junior Clamps provide a compact and dependable repair solution where complete coverage around the pipe is required.

Half Circle

Please note that the Half Circle Clamps shown below are a different product from the Junior Clamps described above.

Unlike a Junior Clamp, which wraps completely around the pipe, a Half Circle Clamp covers only part of the pipe’s circumference. It is intended primarily for localised repairs, such as pinhole leaks in smaller-diameter pipes. Half Circle Clamps are also available in 75 mm and 150 mm lengths.
