424722-2 supersedes older part numbers: 424480-0
Genuine Makita part 424722-2 — Fitting Rubber (DX01/DX02). This flexible rubber gasket seals the inlet/collector area on Makita’s DX01 and DX02 on‑tool dust extraction units, restoring the snug connection that keeps dust flowing into the extractor instead of escaping at the joint.
Designed as the original Makita sealing piece for the collector base, it’s the exact replacement used in the DX01/DX02 assemblies and appears on Makita parts lists and exploded diagrams for those units.
Example compatible tools/assemblies: the DX01/DX02 dust extractors themselves and Makita combination/rotary hammers that use those extractors or the integrated dust-collection interfaces.
Simple to fit — the part slips into the collector base/pipe cover area to restore the rubber-to-plastic seal that the dust extractor needs to maintain suction. If your dust collection isn’t sealing or the inlet gasket is torn or missing, this genuine Makita replacement is the exact power tool parts item to get your extractor sealing correctly again.
