The Wacker Neuson 5100011501 is a genuine OEM O-Ring Seal designed for the RD-series walk-behind and ride-on tandem rollers. This part is sourced directly from Wacker Neuson, ensuring it meets the exact dimensional and material specifications of the original component. Fitment covers the full RD18, RD24, RD27, and RD28 tandem roller families, including standard, combination (O), and padfoot/combination (C) drum configurations across multiple serial-number ranges. If your machine is running a worn or damaged O-Ring Seal, replacing it promptly with part number 5100011501 keeps fluid circuits sealed and the roller operating at full capacity.
Key Features
- Genuine OEM Elastomer Grade — Manufactured to Wacker Neuson's original material and durometer specifications, delivering the compression and chemical resistance required for hydraulic and fluid sealing in tandem roller applications.
- Drop-In Replacement — Matches the original groove dimensions exactly, seating without modification into the same bore or port as the factory seal.
- Broad RD-Series Coverage — Fits the RD18-80, RD18-100, RD24-100, RD27-120, and RD28-120 tandem roller families in standard, O, and C drum variants, including US and SE market units.
- Leak Prevention Where It Counts — A correctly seated O-Ring Seal maintains system pressure in hydraulic circuits; a failed or extruded seal causes fluid loss, pressure drop, and potential damage to downstream components.
- Fluid Compatibility — Formulated to resist degradation from the hydraulic fluids used in Wacker Neuson RD-series drive and vibration systems, holding its seal integrity across normal operating temperature ranges.
An O-Ring Seal creates a static or dynamic pressure-tight barrier between two mating surfaces or within a ported housing, preventing hydraulic fluid, oil, or coolant from bypassing the intended flow path. In tandem rollers like the RD-series, these seals are critical throughout the hydraulic drive and vibration circuits, where sustained pressure and heat cycling are constant. When an O-Ring Seal hardens, cracks, or becomes extruded from its groove, the resulting leak reduces system pressure, accelerates component wear, and can lead to unplanned downtime on compaction jobs.
