The Wacker Neuson 5100011515 is a genuine OEM O-Ring Seal designed for the RD18, RD24, and RD28 tandem rollers and the RC50 single-drum soil compactor series. As a factory-sourced component, the 5100011515 is manufactured to the exact material and dimensional specifications required for these machines, ensuring a correct, leak-free seal every time. This O-Ring Seal covers an extensive range of variants across the RD18-80, RD18-100, RD18-100c, RD24-100, RD28-120, RC50, and RC50p model lines, including US and SE configurations. When seal integrity matters on demanding compaction equipment, using the correct OEM part is the straightforward choice.
Key Features
- OEM Material Specification — Sourced directly from Wacker Neuson, this O-Ring Seal is manufactured to the correct compound grade and cross-section dimensions required to maintain a pressure-tight seal in these hydraulic and mechanical systems.
- Drop-In Replacement — The 5100011515 seats into the original groove geometry without modification, restoring the sealed interface to as-built condition on all covered variants.
- Broad Model Coverage — Fits RD18-80, RD18-100, RD18-100c, RD24-100, and RD28-120 tandem rollers, as well as RC50 and RC50p single-drum soil compactors, including US, SE, and electric drive configurations.
- Prevents Fluid Loss and Contamination — A degraded or extruded O-Ring allows hydraulic fluid or lubricant to escape the sealed cavity and permits contaminants to enter, accelerating wear on surrounding components and leading to system pressure loss.
- Fuel and Hydraulic Fluid Compatibility — Engineered to resist degradation from the hydraulic oils and fluids used in Wacker Neuson compaction equipment, maintaining elasticity and sealing force through repeated pressure cycles.
An O-Ring Seal creates a static or dynamic fluid-tight barrier between two mating surfaces or within a bore, preventing hydraulic fluid, lubricant, or other media from escaping the system. In compaction equipment like tandem rollers and single-drum soil compactors, O-Rings are used throughout the hydraulic drive circuits, vibration systems, and lubricated housings where pressurized fluid must be contained. When an O-Ring ages, hardens, or is damaged during service, the resulting leak can cause pressure drop in the hydraulic system, erratic drum vibration, or contamination of lubricant cavities — all of which degrade compaction performance and can lead to more extensive component damage if left unaddressed.
