The Wacker Neuson is a genuine OEM Relief Valve Seal Set designed for the RD12-90 and RD12A-90 series tandem rollers. As a factory-sourced component, this seal set is manufactured to the same specifications as the original part it replaces, ensuring consistent hydraulic system performance across all covered configurations — including solid ROPS and foldable ROPS variants. Confirm your machine's model number before ordering to ensure compatibility with your specific RD12 or RD12A configuration.
Key Features
- Genuine OEM Sealing Materials — Sourced directly from Wacker Neuson, this seal set uses the same compound grades and tolerances as the original relief valve seals, maintaining correct compression and leak-free performance under hydraulic pressure.
- Direct-Fit Replacement — Engineered to match the original relief valve assembly geometry on RD12-90 and RD12A-90 rollers, allowing straightforward installation without reworking the valve body or adjacent hydraulic components.
- Broad RD12 Series Coverage — Compatible with RD12-90 and RD12A-90 tandem rollers across multiple configurations, including solid ROPS, foldable ROPS, and green drum variants.
- Restored Hydraulic Pressure Integrity — A failed or worn relief valve seal allows hydraulic fluid to bypass or leak, causing erratic drum drive behavior and loss of compaction force. Replacing this seal set restores proper pressure regulation and consistent drum output.
- Fuel and Fluid System Safety — A compromised relief valve seal can lead to uncontrolled hydraulic pressure fluctuations, placing stress on downstream components. Replacing seals promptly keeps the hydraulic circuit operating within design limits.
The relief valve in a tandem roller's hydraulic system acts as a pressure safety gate — it opens to divert fluid when system pressure exceeds a set threshold, protecting pumps, motors, and lines from damage. The seals within this valve are what maintain a controlled, leak-free closure under normal operating pressure. When these seals wear or degrade, hydraulic fluid can bypass the valve internally, causing pressure loss, overheating, and unpredictable drum drive performance. Replacing the seal set at the first sign of leakage or pressure irregularity is the most cost-effective way to restore full hydraulic function to the roller.
