1. An apparatus for applying an at least two-component viscous material to workpieces, having a metering unit (12) that has a number of metering valves (22) that corresponds to the number of components of the viscous material, and having a static mixer (14) that has a mixing tube (26) for mixing the components, which are introduced, by means of the metering unit (12), into a material inlet (28) at its first end, passing through from the material inlet (28) to a material outlet (30) at its second end, and an outer tube (24), wherein the mixing tube (26) is accommodated in the outer tube (24), and sealed off, relative to the environment, at the material inlet (28) and the material outlet (30), in each instance, by means of a seal (48), wherein the seals (48) have a circumferential cutting edge (50), in each instance, and wherein the cutting edges (50), when subjected to a force toward one another, cut into an end face (52) on the mixing tube (26), in each instance.
