The Wacker Neuson Water Tank Plug is a genuine OEM component designed for BFS and BFSX series floor saws, including the BFS16, BFS18, BFS18D, BFS20, BFS20D, BFSX16, BFSX18, BFSX18A, BFSX18D, BFSX20, BFSX20A, and BFSX20D models. As a factory-sourced part, the is manufactured to the exact dimensions and material specifications Wacker Neuson requires — ensuring a proper seal every time. This is the correct OEM replacement when the original plug is lost, damaged, or leaking, and it installs directly in place of the original without any modification. Keeping the right plug in place protects the water system and helps your saw perform consistently across demanding cutting applications.
Key Features
- OEM Sealing Integrity — Manufactured to Wacker Neuson's exact thread pitch and material spec, ensuring a leak-free seal on the water tank port every time the plug is seated.
- Direct Drop-In Replacement — Threads directly into the original water tank port with no adaptation needed; matches the factory fitting on all listed BFS and BFSX floor saw variants.
- Broad BFS and BFSX Series Coverage — A single part number covers the BFS16, BFS18, BFS20, and the full BFSX lineup including A, D, and RAW configurations.
- Protects Water System Function — A failed or missing tank plug allows water to escape or contaminants to enter, disrupting the blade cooling flow that floor saws depend on during concrete and asphalt cutting.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, so part number 5000402464 matches the OEM bill of materials for every compatible model listed.
The water tank plug seals the fill or drain port on the floor saw's onboard water tank — the system that delivers a steady flow of water to the blade during cutting. This water flow controls blade temperature and suppresses dust, both of which are critical to cut quality and blade longevity. When the plug is cracked, cross-threaded, or missing entirely, the tank loses pressure or drains unexpectedly, interrupting water delivery to the blade and potentially causing overheating or premature blade wear.
