Slip-on-sleeve with KRASO 4 Seal
+ The surrounding KRASO 4 Seal is joined to the pipe penetration force-fit this prevents creep or slippage. Due to the special geometry our KRASO 4 Seal produces a grip with the concrete.
+ Altogether this results in a water pressure tightness up to 10 bar - MPA-tested! The KRASO4 Seal also protects against the naturally occurring nobel gas radon and by this prevents a concentration of the radioactive gas in indoor spaces.
+ All pipe penetrations are also available as KG 2000 with thermally welded KRASO 4 Seal.
