Use Case

This seal is essential if you notice reduced suction, air hissing sounds near the cyclone assembly, or visible wear on the existing seal. It's a critical maintenance part for DC25 owners looking to restore their vacuum to factory performance specifications. Replacing a worn cyclone seal is often more cost-effective than repairs involving motor head replacement.
