The Wacker Neuson Seal is a genuine OEM seal designed for the RD18-80, RD18-100, RD18-100 C, RC110, and RC110P series tandem rollers and compactors. As a factory-sourced component, this seal is manufactured to the exact specifications required by Wacker Neuson, ensuring a correct, consistent fit across the full range of compatible machines. It covers an extensive lineup of RD18 and RC110 variants, including US, SE, and CAB configurations. When your original seal wears out or begins to leak, replacing it with part restores proper sealing function and helps keep your compactor operating as intended.
Key Features
- OEM Material Grade — Manufactured to Wacker Neuson's compression and elasticity standards for this seal position, delivering the same sealing integrity as the part that left the factory.
- Drop-In Replacement — Engineered to the original profile and dimensions, this seal seats into position the same way as the factory part, with no reworking of the housing or mating surfaces.
- Broad Model Coverage — Fits RD18-80, RD18-100, and RD18-100 C tandem rollers across standard, US, SE, and .3-series variants, plus RC110 and RC110P compactors in standard, US ROPS, and US CAB configurations.
- Fluid Containment Where It Counts — A properly functioning seal prevents fluid migration between internal systems, protecting bearings, shafts, and adjacent components from contamination and accelerated wear.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5100011729 carries the full assurance of an authorized OEM component, not an approximation.
A seal in a tandem roller or compactor serves as a barrier that keeps hydraulic fluid, lubricant, or other operating media confined to their intended circuits and chambers. When a seal degrades — through heat cycling, mechanical wear, or chemical breakdown — it can allow fluid to escape or contaminants to enter, which puts pressure on surrounding components and can lead to more extensive mechanical damage over time. Replacing a worn seal promptly with the correct OEM part is one of the most straightforward ways to protect the larger assembly and maintain consistent compaction output on the job.
