PTFE-coated filling nozzle supplied as a replacement part for the 2000-0309-0000 filling device. The nozzle is positioned between the static mixer and the cartridge: the mixed material is dispensed through a static mixer of the 0001-9998-1236 series directly into empty plastic cartridges with a pre-assembled plunger (0001-4900-0310OK). The PTFE coating minimizes material adhesion, allowing the nozzle to be cleaned without residue and reused. Chemically resistant and also suitable for aggressive media.
