The Wacker Neuson 5100018719 is a genuine OEM Water Hose designed for the RD7 series walk-behind tandem rollers, covering the RD7A, RD7H, RD7He, and RD7Ye model variants. As a factory-sourced component, this hose is produced to the exact material and dimensional specifications used in original assembly, ensuring a correct, leak-free connection within the machine's water system. Confirm your model number before ordering — this part spans a wide range of RD7 configurations, and matching to your specific serial number range guarantees the right fit. Keep your roller's drum wetting system operating as intended with this direct OEM replacement.
Key Features
- OEM-Grade Hose Material — Manufactured to Wacker Neuson's original compound and wall-thickness specifications, resisting the heat, pressure, and vibration cycles typical of tandem roller operation.
- Direct-Fit Replacement — Molded to match the original routing path and end connections on RD7 series rollers, so installation follows the same procedure as the factory-fitted hose with no trimming or adapter fittings needed.
- Broad RD7 Series Coverage — Compatible across RD7A, RD7H, RD7He, and RD7Ye tandem roller variants, including both North America-specific and standard production configurations.
- Protects Drum Wetting Performance — A sound water hose delivers consistent flow to the drum wetting system; a cracked or leaking hose starves the drums of water, causing asphalt pickup and surface defects during compaction passes.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5100018719 carries the same quality assurance as the component installed at the factory.
The water hose on a tandem roller carries water from the machine's onboard tank to the drum wetting system, where a continuous film of water prevents hot asphalt from sticking to the steel drums during compaction. Without reliable flow through this hose, the drums pick up material, leaving tears and imperfections in the mat surface. A hose that has cracked, collapsed, or developed a leak at its fittings will reduce or cut off that flow entirely, so replacing a worn hose promptly is essential to maintaining finish quality on asphalt paving work.
