Service penetration for plastic pipes that can also be installed around existing pipes

  • Simple to install
  • Can be installed into light-frame walls and walls and intermediate floors made of rock materials.
  • In walls the cuffs must be installed on both sides of the penetration, in intermediate floors the cuff is only needed on the underside of the floor.
  • The cuff can be surface or flush mounted. When opting for the surface installation, attention must be paid to attaching the cuff to the structure according to the product approval.
  • Up to the pipe size of 110 mm, the cuffs can be installed so that they touch each other, but with pipes larger than 110 mm the distance between the cuffs must be at least 100 mm.

Possible gaps between the line pipe and the structure must be sealed with concrete, plaster or mineral wool before attaching the cuff.
