The Wacker Neuson 5100031211 is a genuine OEM Water Hose designed for the RD7 series walk-behind tandem rollers, including the RD7A, RD7H, RD7He, and RD7Ye models. As a factory-original component, this hose is manufactured to the exact routing, diameter, and connection specifications required by the machine — no guesswork on fit or compatibility. Wacker Neuson genuine OEM parts are produced to the same standards as the components originally installed at the factory, ensuring that your roller performs as it was designed to. If you are servicing or restoring water system function on an RD7-series tandem roller, part number 5100031211 is the correct replacement to specify.
Key Features
- Genuine OEM Construction: — Factory-original hose material and wall thickness ensure correct flow rate and pressure handling within the RD7 drum water system — not a generic hose cut to length.
- Direct-Fit Replacement: — Molded or cut to match the original routing path, with connections that seat correctly to existing fittings without adapter hardware.
- Broad RD7 Series Coverage: — Confirmed fitment across RD7A, RD7H, RD7He, and RD7Ye tandem roller variants, including multiple machine configurations in both North American and standard build specifications.
- Protects Drum Wetting Performance: — A failed or cracked water hose starves the drum wetting system of flow, causing asphalt to stick to the drum surface and compromising compaction quality. This replacement restores consistent water delivery to the drums.
- Verified Part Number Fit: — Sourced directly from Wacker Neuson, part 5100031211 is cross-referenced against multiple RD7 machine numbers to confirm accuracy before listing.
The water hose on an RD7 tandem roller is part of the drum wetting system, which delivers a controlled flow of water to the surface of the compaction drums during asphalt paving and rolling operations. Keeping the drums wetted prevents hot asphalt mix from adhering to the steel drum surface, which would otherwise cause tearing, uneven compaction, and surface defects in the mat. When this hose cracks, kinks, or loses a connection, water delivery is interrupted — leading to drum pick-up, wasted material, and rework. Replacing a worn or damaged hose promptly keeps the wetting system functioning correctly and maintains the quality of the finished surface.
