What this gasket does
The Rocket undercup gasket H8 C449900229 is a sealing component fitted beneath the cup support area of the machine. It provides a tight seal that prevents water or steam from escaping at this connection point, helping keep the brewing process stable and leak-free.
Signs it needs replacing
Over time, gaskets lose their elasticity due to repeated heat exposure and pressure cycles. This can lead to visible dripping, seeping moisture around the cup support, or a noticeable drop in performance. A hardened, cracked, or flattened gasket is a clear sign that replacement is due.
