Wacker Neuson 5000080731 O-Ring .468 X .078 Duro90 3-906

The Wacker Neuson is a genuine OEM O-Ring.468 X.078 Duro90 3-906 designed for a wide range of Wacker Neuson tandem rollers, trench rollers, and related equipment including the RD12, RD16, RT56, RT82, RTL82, RTLx, and RTKx series. As a direct OEM replacement, part is manufactured to the exact material grade and dimensional tolerances specified for these machines. Fitment also extends to RD7 series tandem rollers and select CRT ride-on trowel and WB16 power buggy models — always confirm your machine number before ordering.

Key Features

• 90 Durometer Compound: — The Duro90 rating means this O-ring is formulated from a high-hardness elastomer engineered to resist extrusion under the elevated hydraulic pressures found in roller and trench roller hydraulic systems.
• Exact OEM Dimensions: — At .468 inches inner diameter and .078 inches cross-section, this ring seats into its groove without shimming, trimming, or adaptation, maintaining a consistent seal geometry on installation.
• Genuine Wacker Neuson OEM Part: — Sourced directly from Wacker Neuson, part number 5000080731 meets the original design specification for material grade, hardness, and compression set resistance — critical qualities for a hydraulic sealing component.
• Broad Roller and Trench Roller Coverage: — Confirmed fitment across RD12, RD16, RD7, RT56-SC, RT82-SC, RT56-SC2, RT82-SC2, RTL82-SC3, RTLx-SC3, and RTKx-SC3 series machines, covering multiple production variants and configurations.
• Hydraulic Integrity Protection: — A correctly seated O-ring maintains hydraulic circuit pressure and prevents fluid bypass. A worn or degraded O-ring leads to internal leakage, loss of drive or vibration performance, and potential hydraulic system contamination.
• Fuel and Fluid System Safety: — Using an O-ring of the correct durometer and dimensions is essential in hydraulic applications; an undersized or incorrect-hardness seal can fail under pressure, creating a fluid leak that poses both an operational and safety risk.

An O-ring is a precision sealing element used throughout hydraulic circuits, fluid ports, and valve assemblies to prevent internal and external fluid leakage. In roller and trench roller equipment, O-rings maintain pressure integrity across hydraulic drive, vibration, and steering circuits — allowing the machine to deliver consistent compaction force and directional control. When an O-ring deteriorates due to heat cycling, chemical exposure, or compression set, it loses its ability to seal effectively, resulting in hydraulic fluid loss, pressure drop, and accelerated wear on surrounding components.
