The sealing ring is made of high-quality materials and has excellent durability and sealing performance. [Durable and efficient]: The aging and wear of the seals will affect the suction performance of the vacuum cleaner, resulting in the inability to collect dust or overflow, and the dust collection effect will worsen. Therefore, it is necessary to regularly replace the dust box seal to improve the performance of the vacuum cleaner. [Suggestion]; The fixed sealing ring on the top of the Dyson V11 dust box does not contain screws. Please keep it after removing it. When installing, turn the screw until there is no play. Do not turn the screw too hard, otherwise you will damage the inner bore of the washer. [Package Included]: 1 x Dyson V11 Washer
