The Wacker Neuson 5100011736 O-Ring Seal is a genuine OEM sealing component designed for the RD-series tandem rollers and RC110 single-drum soil compactors. As a direct OEM replacement, this O-Ring Seal is manufactured to the exact material and dimensional specifications required for proper sealing performance across the full range of compatible machines. Fitment covers a wide span of the Wacker Neuson roller lineup, including RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller variants, as well as RC110 US ROPS and RC110 US CAB compactors. Stocking the 5100011736 as a service part keeps your compaction equipment ready for scheduled maintenance and unplanned seal replacements alike.
Key Features
- Genuine OEM Sealing Material — Manufactured to Wacker Neuson's specified elastomer compound, ensuring the correct compression set and chemical resistance for hydraulic and fluid-contact applications in compaction equipment.
- Drop-In Dimensional Fit — Matches the exact cross-section and inner diameter of the original seal, seating correctly in the groove without modification or shimming.
- Broad RD and RC Series Compatibility — A single part number covers RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller variants, plus RC110 US ROPS and RC110 US CAB soil compactors, including DPF, open-drum, and combination configurations.
- Prevents Fluid Leak Paths — A correctly seated O-Ring Seal maintains system pressure and keeps hydraulic fluid or lubricants contained, preventing contamination of surrounding components and loss of operating efficiency.
- Supports Scheduled Seal Service — O-ring replacement at recommended intervals is a low-cost step that protects higher-value hydraulic components from the damage caused by a degraded or extruded seal.
An O-ring seal is a circular elastomeric ring that sits in a machined groove and creates a pressure-tight barrier between two mating surfaces or around a shaft or port. In compaction equipment like the RD-series tandem rollers and RC110 compactors, O-ring seals are used throughout the hydraulic system, drum drive assemblies, and fluid reservoirs to prevent leaks and maintain the operating pressures that drive compaction performance. When an O-ring degrades — through heat cycling, compression set, or chemical exposure — it loses its ability to seal, leading to fluid loss, pressure drop, and potential damage to downstream components. Replacing a worn O-ring promptly with the correct OEM part restores the integrity of the sealed system and protects the surrounding assembly.
