The hard pipe sleeve including two plugs is the basis for the PYROPLUG Shell cable seal and is suitable for creating small, round cable seals in lightweight partition walls. The seal system is tested and approved for fire resistance classes S90 according to DIN 4102-9. The application areas and approval data can be found in the usability certificates. After completing the installation, the remaining joints between the cables, plugs and pipe sleeve must be sealed with the FBA-SP filler (to be ordered separately) in accordance with the proof of usability.
