Wall Crossing

  • Description :
    Wall crossings are rubber seals used to connect all types of pipe on manholes, buildings or other concrete structures.

They are made from SBR (styrene butadiene rubber), hardness 40 ± 5° IHR (indicative value). Wall crossings must be used at every feedthrough (valve chamber, entering buildings, etc.) so that the pre-insulated tube can expand through the wall without damage.
  • Diameters: ND 20 to 1000
