The Wacker Neuson 5100012778 is a genuine OEM Flexible Tubing designed for the RD18 series tandem rollers and RC70vo single-drum soil compactor. Sourced directly from Wacker Neuson, this part carries the same specifications as the original component installed at the factory, ensuring a correct, drop-in fit across all compatible RD18 configurations. This tubing is confirmed to fit the RD18-80, RD18-100, RD18-100c, and RC70vo models, covering standard, SE, US, and.3-revision variants. When your original flexible tubing cracks, hardens, or develops leaks, replacing it promptly with the correct OEM part keeps fluid or air routing operating as intended and protects downstream components from damage.
Key Features
- Genuine OEM Material Grade — Produced to Wacker Neuson's original tubing specification, with the correct flexibility, inner diameter, and pressure tolerance for this application — not a universal hose cut to length.
- Direct Replacement Routing — Matches the original routing path and end fittings of the 5100012778, so it connects to existing ports and brackets without modification.
- Broad RD18 and RC70vo Coverage — Fits the full RD18-80, RD18-100, and RD18-100c model families across standard, SE, US, and .3-revision builds, plus the RC70vo single-drum compactor.
- Protects System Integrity — A failed or cracked flexible tubing allows fluid or air to escape the circuit, leading to pressure loss, overheating, or contamination of adjacent systems — replacing it restores proper circuit performance.
- Verified OEM Part Number — Cross-referenced to Wacker Neuson part number 5100012778, so you can order with confidence that this is the correct tubing for your machine.
Flexible tubing on Wacker Neuson tandem rollers and soil compactors serves as a routed conduit for hydraulic fluid, coolant, or air between fixed and moving machine sections — depending on its location in the system. Because rollers and compactors generate significant vibration during operation, rigid pipe connections are not practical at every junction; flexible tubing absorbs movement and prevents fatigue cracking at connection points. When this tubing deteriorates — through heat cycling, abrasion, or age — it can weep fluid, collapse internally, or rupture, disrupting circuit flow and potentially causing more extensive damage to pumps, motors, or cooling components downstream.
