The Wacker Neuson Water Tank Cap is a genuine OEM component designed for CB14B-900 and CB14B-1000 series soil and asphalt compactors. Sourced directly from Wacker Neuson, this cap is manufactured to the same specification as the original part fitted at the factory, ensuring a correct, secure seal on the water tank. It is a direct replacement for worn, cracked, or missing caps across the full CB14B series lineup. Verified fitment spans multiple build variants of the CB14B-900 and CB14B-1000, making this the right choice when you need a dependable part with no guesswork.
Key Features
- OEM Seal Integrity — Manufactured to Wacker Neuson's original specification, ensuring the cap forms a proper pressure-retaining seal on the water tank without leaks or fitment gaps.
- Direct Drop-In Replacement — Matches the original tank neck thread pattern and cap profile on CB14B series compactors for straightforward installation.
- Broad CB14B Series Coverage — Confirmed fitment across multiple CB14B-900 and CB14B-1000 build variants used in soil and asphalt compaction applications.
- Protects Water System Function — A secure, intact cap keeps the water tank pressurized and contaminant-free, supporting consistent water flow to the compaction drums during operation.
- Genuine Wacker Neuson Part — Part number 5200003051 is an authentic OEM component, giving you confidence that the part matches the original in material grade and dimensional tolerancing.
The water tank cap seals the opening of the water tank on vibratory compactors, maintaining the system's ability to deliver a steady supply of water to the drum surfaces. This water flow prevents asphalt and soil from sticking to the drums during compaction passes. When the cap is damaged, missing, or no longer sealing correctly, the tank can lose pressure, allow debris contamination, or permit water to leak — all of which interrupt the wetting cycle and reduce compaction efficiency. Replacing a faulty cap promptly keeps the water system operating as intended and protects the broader tank assembly from damage.
