The Wacker Neuson 5100012221 is a genuine OEM Flexible Tubing designed for the RD40-130 and RD45-140 series tandem rollers, including standard, combination drum, offset drum, DPF-equipped, and US-market variants. As a factory-sourced component, the 5100012221 is manufactured to the exact specifications required by these machines, ensuring correct routing, secure connections, and consistent performance across the full range of covered models. This genuine OEM part is backed by Wacker Neuson's parts program and is the same component installed during original production. Confirm your machine's model number before ordering to ensure compatibility with your specific RD40-130 or RD45-140 configuration.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original material and dimensional specifications, delivering the correct flexibility, temperature resistance, and wall integrity for fluid or air routing in tandem roller applications.
- Drop-In Replacement: — Engineered to match the original routing path, end fittings, and connection points of the RD40-130 and RD45-140 series, so installation follows the standard service procedure without modification.
- Broad Series Coverage: — Compatible with a wide range of RD40-130 and RD45-140 configurations, including standard, combination drum (C), offset drum (O), DPF-equipped, and US-market variants.
- Maintains System Integrity: — A sound, correctly routed flexible tube keeps fluid or air delivery consistent; a cracked, kinked, or deteriorated tube can cause pressure loss, leaks, or system contamination that affects roller performance.
- Verified OEM Part Number: — Sourced directly under part number 5100012221, eliminating guesswork when cross-referencing against Wacker Neuson service documentation and parts diagrams.
Flexible tubing serves as a routed conduit for fluids or air within the machine's operating systems — such as hydraulic, fuel, water sprinkling, or cooling circuits — allowing movement and vibration between connected components without cracking or separating. In tandem rollers like the RD40-130 and RD45-140, these tubes must withstand continuous vibration, temperature cycling, and exposure to hydraulic fluid or water. When flexible tubing degrades, it can develop cracks, pinhole leaks, or collapsed walls that restrict flow, cause pressure drop, or allow contamination to enter the system — all of which can impair roller function or lead to broader component damage if left unaddressed.
