The Wacker Neuson Pressure Relief Kit is a genuine OEM Pressure Relief Kit designed for the RD12A-90 and RD12-90 series tandem rollers. Sourced directly from Wacker Neuson, this kit meets the exact specifications of the original component it replaces, ensuring correct pressure regulation within the hydraulic system. It is confirmed to fit multiple RD12A-90 and RD12-90 configurations, including standard, foldable ROPS, and solid ROPS variants.
Key Features
- OEM-Calibrated Relief Pressure — Manufactured to the precise pressure threshold specified for the RD12 series hydraulic circuit, preventing under- or over-relief that can damage system components.
- Direct-Fit Hydraulic Connection — Engineered to match the original port sizing and thread specification, allowing straightforward installation without adapters or rework.
- Broad RD12 Series Coverage — Fits RD12A-90 and RD12-90 tandem rollers across standard, solid ROPS, and foldable ROPS configurations.
- Protects Hydraulic System Integrity — A correctly functioning pressure relief kit prevents dangerous pressure spikes that can rupture hoses, damage pumps, or cause uncontrolled drum behavior on the compaction circuit.
- Genuine OEM Quality — Supplied as an authentic Wacker Neuson part, backed by the manufacturer's standards for material grade, seal compatibility, and valve tolerancing specific to this hydraulic application.
A pressure relief kit regulates maximum hydraulic pressure within the machine's drive or compaction circuit by venting excess fluid once a set pressure threshold is reached. This protects pumps, motors, hoses, and valves from damage caused by pressure spikes that occur during normal operation or sudden load changes. When the relief valve wears or fails, the system may run at uncontrolled pressures — leading to sluggish drum response, overheating, or accelerated wear on expensive hydraulic components throughout the roller.
