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 meets the exact specifications of the original part it replaces. It is confirmed compatible across the RD10, RD15, and RD25 roller series, making it a straightforward service replacement for operators running any of these machines. Verifying your model number against part number before ordering ensures a direct, hassle-free installation.
Key Features
- Genuine OEM Sealing Integrity — manufactured to the same material and thread specification as the original cap, ensuring a secure, leak-free seal on the water tank.
- Direct Drop-In Replacement — threads directly onto the existing water tank fitting with no rework or adaptation needed at installation.
- Confirmed Fitment for RD Series Tandem Rollers — verified for use on RD10, RD15, and RD25 hydrostatic double drum vibratory rollers.
- Protects Water System Performance — a properly sealing tank cap keeps the drum wetting system pressurized and free of contamination, supporting consistent water flow to the drums during asphalt compaction passes.
- Fuel and Fluid Safety Compliance — a compromised or missing water tank cap can allow debris ingress and system contamination; replacing it promptly maintains safe, clean system operation.
The water tank cap seals the onboard water reservoir that feeds the drum wetting system on tandem rollers. During asphalt compaction, water is continuously distributed across the drum surfaces to prevent the hot mix from sticking — a function that depends entirely on the tank remaining sealed and pressurized. A cracked, stripped, or missing cap allows debris into the water system and disrupts consistent water flow, which can lead to mat pickup and surface defects on the finished pavement.
