As a Swiss company, STRAUB stands for premium pipe couplings, which are used worldwide in various fields of applications.
STRAUB Werke AG in Wangs, Switzerland was setting more than 40 years ago a milestone with its pioneering accomplishment in pipe connection technology. With more than 40 years of experience in the field of production of various solutions for joining and reparations of pipes for waterworks, industrial applications, shipbuilding, offshore, renewable energy sources.

Why Use Straub Pipe Couplings?

  • Simple and quick assembly without preparation of tube ends
  • Minimal space required when mounting the coupling
  • The small weight of the coupling
  • Without time impacts
  • No aftermath
  • Save space - ideal for narrow parallel pipes
  • Connecting pipes of different materials
  • Perfect sealing on uneven or rough tubes.
  • Swivel coupling for easier access to tensile elements
  • Flexibility in connection - allows scrolling of 5 to 20mm tubes
  • Possible angle deviation up to 12 °; Static and dynamic
  • Compensates deviations in outer diameter of tubes up to 30mm
  • Compensates landslide
  • Reduces vibration, noise and pressure injuries
  • No use of flames - no fire hazard
  • Fast removal
  • Effective remediation options
