The Wacker Neuson Air Hose is a genuine OEM component designed for the RD40-130 and RD45-140 series tandem rollers. As a direct OEM replacement, this air hose is manufactured to the same specifications as the original part, ensuring a correct, trouble-free installation with no guesswork. It is compatible across the full RD40-130 and RD45-140 model range, including standard, C, and O variants, as well as the updated.3-series machines. Sourcing the genuine Wacker Neuson means you are getting a part built to perform exactly as the original did from day one.
Key Features
- OEM-Grade Hose Construction — Built to the same pressure tolerance and material spec as the original, ensuring consistent airflow delivery without cracking, kinking, or premature wear.
- Direct-Fit Replacement — Engineered to match the original routing, diameter, and end connections, so the hose seats correctly without adapters or trimming.
- Broad RD-Series Compatibility — Fits RD40-130 and RD45-140 tandem rollers across standard, C, O, and .3-series variants, covering a wide range of Wacker Neuson compaction equipment.
- Sustained Air System Performance — A fully intact air hose maintains proper air pressure to the machine's systems; a cracked or failed hose leads to pressure loss, erratic operation, and accelerated wear on connected components.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5100012308 carries full OEM traceability, giving you confidence that you are installing the correct component for your machine.
The air hose routes compressed air to the necessary systems within the tandem roller, maintaining the pressure required for consistent machine operation. When the hose degrades — through cracking, splitting, or connection failure — air pressure drops, which can cause erratic performance or prevent critical systems from functioning altogether. Replacing a worn hose promptly with the correct OEM part restores proper airflow and keeps the roller operating as intended.
