Empty conduit closure

Empty conduit closure

Gas tight seal of the empty conduit. Particularly necessary in sewage treatment plants, since corrosive gases from the sewage treatment system can otherwise enter the building or penetrate into the control system. The closure of the empty conduit is possible using polyurethane foam (special foam) or better, with special seals.
