VSH PowerPress Gas reduced coupling (2 x press)


VSH PowerPress Gas® C9439G is a reducer designed for thick wall steel pipe. By using VSH PowerPress Gas® system installation times are reduced significantly and a clean working environment is assured. The range consists of DW-profile press fittings and valves in sizes ½" up to and including 2".

  • outstanding corrosion resistance due to ZnNi coating
  • clear identification of materials and dimensions
  • Visu-Control-ring and Leak Before Pressed-function
