The Wacker Neuson Seal is a genuine OEM seal designed for the RD18-80, RD18-100, and RD18-100C series tandem rollers. As a factory-sourced component, it meets the exact material grade and compression specifications Wacker Neuson engineers to for this application — ensuring the seal performs the way it was intended to from day one. Part number covers an extensive range of RD18 series configurations, including US and SE variants, giving you confidence that you're ordering the correct part for your machine. Keep a spare on hand and avoid unplanned delays when routine service comes due on your roller fleet.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's specified compound and compression rating for this application, not a generic substitute.
- Drop-In Installation — Engineered to seat correctly in the original groove geometry of the RD18 series, so no trimming, shimming, or adapting is needed during service.
- Broad RD18 Series Coverage — A single part number fits RD18-80, RD18-100, and RD18-100C variants, including US and SE market configurations across multiple production runs.
- Prevents Fluid Migration and Contamination — A healthy seal keeps hydraulic fluid and lubricants where they belong; a worn or cracked seal allows ingress of dirt and moisture that accelerates internal wear.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, so the part number, geometry, and material spec are exactly what the machine was built with.
A seal in a compaction roller serves as a barrier between moving and stationary components, preventing the escape of hydraulic fluid or lubricant and blocking the entry of dirt, water, and debris into sensitive assemblies. On a tandem roller like the RD18 series, seals are critical to maintaining drum drive and vibration system integrity — a leaking or failed seal can lead to fluid loss, overheating, and accelerated wear on the components it was protecting. Replacing a worn seal promptly with the correct OEM part is one of the most cost-effective ways to preserve the long-term reliability of the machine's core systems.
