Sealing of speedpipe with the divisible sealing element: with or without fibre optic cable.
Adjusted to all SRV-G tc and occupancy variants of PE-HD ducts: due to the variable gaskets bundles as well as protective ducts - either empty or occupied with speedpipe / cables - remain clean, dry and operational over decades.
Gas- and water-tight even up to 0.5 bar, the divisible elements fix speedpipe subduct solutions against temperature-affected length modifications.
