Brandless DG firestop collar links 250 VA 131369

DG firestop collar links offer an absolute sealing ring for the space between a pipe or cable and the penetration opening (drilled hole or conduit) for almost all liquids and gases. The firestop collar links are placed around the pipe, fastened together and pushed along the pipe into the penetration opening. Using an Allen key, the bolts are tightened one by one from one side until the sealant material between the pressure plates begins to oose out. The sealant then distributes itself proportionally to the tension and seals the opening completely. Quick and easy installation, thanks to the pre-assembled and pre-formed links. Oil-resistant and non-toxic, approved for drinking water applications (stainless steel). Reliable seal, long service life. Pressure-tight to 2 bar and with adequate support to 6 bar. Can withstand temperatures of 80°C and a short peak temperature of 110 ° C. Absorbs vibrations, shocks and sound.
