Rocket Large Water Tank Gasket – Original Spare Part
Sometimes a small issue only shows itself as a damp spot inside the machine, in a place that should really stay dry. Most of the time, the cause sits at the large gasket between the water tank and the housing.
Rubber gaskets lose their tension over time – every change in temperature takes its toll on the material. A new gasket brings the tank connection back to fully sealed, without needing much in the way of tools or prior knowledge. For us, that's simply part of the normal care of a machine you plan to keep for a long time.
