For more than 35 years the STRAUB pipe joint has been internationally regarded as one of the best innovations in pipe joining technology thanks to its ingenious design. Intensive research and development combined with specialist knowledge and a high degree of technical know-how produced a unique pipe joining system. It can be fitted simply and quickly while still offering great security.

STRAUB-CLAMP provides a safe, reliable way of sealing damaged pipes made from a range of materials (steel, cast iron, ductile cast iron, fibre cement, PVC). Available in sizes from DN 40 to DN 400, and obtainable as a two-piece version, STRAUB-CLAMP repair clamps with the standard NBR sealing sleeve can be used on gas, water and drainage pipes.

    • Ideal for repairing large damaged areas up to 250 mm long.
    • The large-surface waffle profile reduces the required tightening torque, extending the life of the rubber.
    • One size (OD) spans a wide range (up to 20 mm).
    • Integrated ergonomic hand grips for easy handling.
    • No loose screws or parts when opening. Both the one-piece and two-piece repair clamps are complete units.
    • High level of corrosion resistance. Modern manufacturing methods, including pressure jointing, prevent changes in the material structure and stresses in the material.
    • The entire repair clamp is made from stainless steel (1.4301 and 1.4501).
    • The chrome steel screws are coated with Delta Seal, ensuring smooth tightening to the specified torque.
    • Installation with standard tools (torque wrench with hex socket) – without extensions.
    • Swiss quality product
  • One and two-piece clamps for the safe, reliable repair of gas, water and drainage pipes made from a range of materials.
