The Wacker Neuson 5100012788 is a genuine OEM Hose Nozzle designed for the RD-series tandem rollers and RC-series single-drum soil compactors. As a direct OEM replacement sourced through the Wacker Neuson parts program, the 5100012788 meets the same specifications as the original component installed at the factory. This nozzle fits an extensive range of machines across the RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller families, as well as the RC50 and RC70 single-drum soil compactor lines, including cab, ROPS, padfoot, and DPF-equipped variants. Verifying your machine model before ordering ensures a correct, hassle-free installation.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original flow and fitment specifications, ensuring the nozzle delivers consistent water output at the spray bar connection point it was engineered for.
- Direct Drop-In Replacement: — Connects to the existing hose and mounting point on your machine's water system without any reworking of the surrounding assembly.
- Broad Roller and Compactor Compatibility: — Fits RD18, RD24, RD27, RD28, RD40, and RD45 tandem rollers and RC50 and RC70 single-drum soil compactors across multiple configuration variants including C, O, cab, ROPS, padfoot, and DPF models.
- Consistent Drum Wetting Performance: — A properly functioning hose nozzle maintains even water distribution across the drum surface, preventing asphalt or material from adhering and ensuring clean compaction passes.
- Part Number Confidence: — Order with confidence using Wacker Neuson part number 5100012788, cross-referenced across dozens of RD and RC machine numbers for verified application coverage.
The hose nozzle is part of the drum wetting system fitted to tandem rollers and single-drum soil compactors. Its job is to direct a controlled flow of water onto the drum surface during asphalt or soil compaction operations, preventing material from sticking to the steel drum and causing surface defects or uneven compaction. When the nozzle becomes clogged, cracked, or worn, water distribution becomes uneven or stops entirely, leading to material pickup on the drum, irregular mat finish on asphalt paving jobs, and accelerated wear on the drum surface itself. Replacing a faulty nozzle promptly restores proper drum wetting and protects both the machine and the finished surface.
