The Wacker Neuson 5100031210 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 direct OEM replacement, part 5100031210 is manufactured to the exact dimensions and material standards of the original component, ensuring a correct, hassle-free installation. This hose is confirmed compatible across a wide range of RD7 tandem roller configurations, including North America-specific builds. Keep a spare on hand to avoid unnecessary interruptions on active paving or compaction sites.
Key Features
- Genuine OEM Construction — Manufactured to the same hose diameter, length, and pressure tolerance as the original, so flow rate and connection integrity are maintained from day one.
- Drop-In Fitment for RD7 Series Rollers — Engineered specifically for the RD7 tandem roller platform; connects to existing fittings without modification to hose routing or mounting points.
- Broad RD7 Compatibility — Confirmed fitment across RD7A, RD7H, RD7He, and RD7Ye variants, including walk-behind and North America-only double-drum configurations.
- Sustained Water System Performance — A sound water hose keeps drum wetting consistent during asphalt passes; a cracked or leaking hose causes uneven water distribution, leading to material pickup and surface defects.
- Direct OEM Source — Supplied as a genuine Wacker Neuson part, so material grade and fitting compatibility match the original specification without guesswork.
The water hose on an RD7 tandem roller is part of the drum wetting system, which delivers a steady flow of water to the compaction drums during asphalt rolling operations. Keeping the drums wet prevents hot asphalt from sticking to the drum surface, which would otherwise cause tearing and surface damage on the mat. When the hose cracks, kinks, or deteriorates, water delivery becomes inconsistent or stops entirely, compromising finish quality and potentially damaging the asphalt surface being compacted.
