Double shut-off disc
Double shut-off discs are equipped with two solid rubber sealing rings and are used in sewer rehabilitation and cleaning for shutting off unpressurised pipes. They are braced in the pipe by means of a threading device and thus seal the pipe completely. A larger sealing surface is achieved by the separately attached sealing rings.
All shut-off discs are manufactured with one passage which can be closed with a screw-on cap. Alternatively, a coupling can be screwed onto the inch thread to connect a hose. Applicable in all pipe materials for pipe diameters from 36mm to 475mm.
