The Wacker Neuson Set of Seals is a genuine OEM set of seals designed for the RD18-80, RD18-100, RD18-100 C, RC50, and RC50p series tandem rollers and single drum soil compactors. As a direct OEM part, the is manufactured to the exact material grade and dimensional tolerances specified for these machines, ensuring proper compression and fitment across the full range of compatible models. This set covers an extensive range of RD18 and RC50 variants — including DPF CAB and DPF ROPS configurations — making it a versatile service item for fleets running multiple Wacker Neuson compactor models.
Key Features
- OEM-Grade Seal Material — Manufactured to Wacker Neuson's specified compound and compression ratings, ensuring the seals maintain integrity under the hydraulic pressures and operating temperatures typical of compaction equipment.
- Direct Drop-In Replacement — Engineered to the exact dimensions of the original seals, allowing straightforward installation without machining, shimming, or adaptation of mating surfaces.
- Broad Compactor Compatibility — Fits RD18-80, RD18-100, and RD18-100 C tandem rollers, as well as RC50 and RC50p single drum soil compactors, including US-market, SE, DPF CAB, and DPF ROPS variants.
- Prevents Fluid Leakage — A correctly seated set of seals keeps hydraulic fluid contained within the system, maintaining drum drive pressure and steering response. Worn or failed seals lead to fluid loss, pressure drop, and potential component damage.
- Genuine OEM Assurance — Supplied as a complete set under Wacker Neuson part number 5100011959, so every seal in the assembly is replaced together — eliminating the risk of mismatched service life between individual seals.
A set of seals in a compaction roller serves as the barrier that keeps hydraulic fluid and lubricants contained within their respective circuits and housings. On machines like the RD18 tandem rollers and RC50 soil compactors, these seals are critical to maintaining consistent drum drive pressure, proper articulation, and vibration system performance. When seals wear, crack, or harden over time, fluid begins to bypass or escape — leading to sluggish drum response, visible leaks, and accelerated wear on surrounding components. Replacing the full set during a service interval restores the system to its original operating condition and protects the integrity of connected hydraulic and drive components.
