Vetter Bypass Stoppers

The Bypass Stopper range offers an effective solution for stopping a flow of water. Bauer couplings allow rigid or lay flat hose to be connected to the stopper, taking the flow above ground via a pump or by gravity through the area of work. Bypass stoppers are a cost effective alternative to over pumping as well as being easy and effective to use. Inflation is via a hand pump or compressor adapter fitted with a pressure regulator. The maximum operating pressure of 1.5 bar (21psi), enables the stoppers to withstand a back pressure of 0.5 bar (7psi or 5m head) when suitably braced.


  • Durable construction expandable bypass/fluming stopper.
  • Pipe internal diameters from 100mm to 1200mm.
  • Supplied with either 2″, 3″, 4″, 6″ or 8″ Bauer Male coupling, to suit customers requirements.
  • Maximum inflation and back pressure must not be exceeded.
  • Available with a Steel Core or for reduced weight a PE Core
