The permanently elastic, closed-pore foam plugs are the basis for the PYROPLUG Peg cable seal and are suitable for creating round cable seals in solid components. The seal system is tested and approved for fire resistance classes up to S90 according to DIN 4102-9 and the European fire resistance classes up to EI120 according to EN 1366-3. The application areas and approval data can be found in the usability certificates. After installation is complete, the remaining gaps between the cables and the plugs must be sealed with the FBA-SP filler (order separately) in accordance with the proof of usability.
