The Wacker Neuson 5100012040 is a genuine OEM Cooling Water Hose designed for RC and RD series compaction equipment, including the RC50, RC70, RC110 single-drum soil compactors and the RD40-130 and RD45-140 tandem rollers. As a direct OEM replacement, this hose is manufactured to the exact dimensions and material specifications of the original component installed at the factory. It fits across a broad range of configurations within these families, including ROPS, CAB, DPF, padfoot, and US-market variants. Verify your machine's model number before ordering to confirm this is the correct hose for your application.
Key Features
- Genuine OEM Construction — Produced to the exact internal diameter, wall thickness, and rubber compound spec as the original hose, ensuring a pressure-rated seal throughout the cooling circuit.
- Direct-Fit Replacement — Matches the original routing, end fittings, and clamp positions so the hose seats correctly without trimming or adapting.
- Broad Fitment Across RC and RD Families — Compatible with RC50, RC50p, RC70, RC70p, RC70vo, RC110, RC110p single-drum soil compactors and RD40-130, RD40-130c, RD40-130o, RD45-140, RD45-140c, RD45-140o tandem rollers, across standard, DPF, ROPS, and CAB variants.
- Coolant Flow Integrity — A sound cooling hose maintains consistent coolant circulation to the engine; a cracked or collapsed hose restricts flow and can lead to overheating and unplanned engine damage.
- Heat and Pressure Resistance — The OEM-spec rubber compound is rated to withstand the operating temperatures and coolant pressures of the engine cooling system under continuous heavy-duty compaction cycles.
A cooling water hose carries engine coolant between the engine block, radiator, and associated cooling system components. It maintains the flow of coolant needed to regulate engine temperature during operation. When a cooling hose deteriorates — through cracking, swelling, or collapsing under pressure — coolant flow is interrupted and the engine overheats rapidly, risking serious internal damage. Replacing a worn or leaking hose promptly is one of the most cost-effective ways to protect the engine on high-utilization compaction equipment.
