The Wacker Neuson Water Tank Cap is a genuine OEM component designed for the RD10, RD15, and RD25 hydrostatic double drum vibratory tandem rollers. Sourced directly from Wacker Neuson, this cap is an exact match to the original part installed at the factory, ensuring a proper seal on the water tank system. It is confirmed compatible across the RD10, RD15, and RD25 roller series, making it the correct choice when your machine's original cap shows signs of cracking, a degraded seal, or a broken retention mechanism.
Key Features
- OEM Sealing Integrity — Manufactured to the same material and thread specification as the original cap, maintaining a positive, leak-free closure on the water tank.
- Direct Bolt-On Replacement — Threads directly onto the existing water tank filler neck with no modification to the tank or surrounding hardware.
- Broad RD-Series Fitment — Verified for use on the RD10, RD15, and RD25 hydrostatic double drum vibratory tandem rollers.
- Protects Drum Wetting System Function — A secure, intact cap keeps the water tank pressurized and debris-free, allowing the drum wetting system to deliver consistent water flow to the drums during asphalt compaction passes.
- Prevents Contamination — A failed or missing cap exposes the tank to dirt and debris, which can clog spray nozzles and interrupt drum wetting — replacing a worn cap is a fast, low-cost fix that keeps the system running clean.
The water tank cap seals the filler opening of the drum wetting system's water reservoir on Wacker Neuson tandem rollers. This system sprays a controlled film of water across the compaction drums to prevent hot asphalt from sticking during rolling operations. When the cap cracks, loses its seal, or breaks entirely, the tank can lose water through spillage or evaporation, and airborne debris can enter the reservoir and clog the spray nozzles — both of which interrupt smooth, consistent compaction work. Replacing the 5000114443 Water Tank Cap promptly restores the tank's sealed, contamination-free environment and keeps the drum wetting system operating as intended.
