Makita 143677-9 — Valve Stay Complete (original Makita)
Replace the inlet/check valve assembly with this genuine Makita Valve Stay Complete (part no. 143677-9). It’s the molded valve housing used inside the dust box of Makita cordless cleaners to hold the one‑way valve and dust bag interface, with the factory mounting points and valve seat already integrated for a clean, drop‑in replacement. Fits a number of Makita cordless vacuum models — for example CL102D, CL104D, CL107FD, CL114FD, CL121D and DCL142, DCL182, DCL184 — so you can restore proper suction and bag sealing without modifying the tool.
The part is supplied as the complete valve stay (single unit). Note: the sealing packing/gasket is listed as a separate item in Makita parts list (packing 422434‑1), so replace that too if your seal is worn or damaged. Installation is straightforward — it mounts inside the dust compartment where the bag and inlet mate.
What’s included: one original Makita Valve Stay Complete, part number 143677-9, ready to install in compatible Makita cleaner models.
