The Wacker Neuson is a genuine OEM O-Ring 40.94 x 2.62 designed for the RS800 series single drum vibratory rollers. As a factory-sourced component, part delivers the exact dimensional tolerances and material grade needed for a proper hydraulic or fluid-system seal in these machines. This O-Ring is confirmed to fit the RS800, RS800A, RS800H, RSS800A, and RS800V walk-behind roller models. Keeping the correct seal in place protects surrounding components and maintains the operational integrity of the roller's fluid systems.
Key Features
- Exact Dimensional Match: — Manufactured to the precise 40.94 x 2.62 mm cross-section spec, ensuring full contact sealing against mating surfaces in the RS800 roller's fluid system.
- Genuine OEM Material Grade: — Sourced directly from Wacker Neuson, this O-Ring uses the correct elastomer compound to withstand the operating temperatures and fluid exposure found in RS800 series rollers.
- Broad RS800 Series Coverage: — A single part number covers the RS800, RS800A, RSS800A, RS800H, and RS800V single drum vibratory roller variants, making it the right seal choice across the family.
- Leak Prevention Where It Counts: — A correctly seated O-Ring maintains system pressure and prevents fluid leaks that can lead to hydraulic loss, contamination, or accelerated wear on nearby components.
- Direct Drop-In Replacement: — Matches the original installed part in geometry and durometer, so it seats cleanly into the existing groove without rework or modification to the housing.
An O-Ring is a circular elastomeric seal installed in a machined groove between two mating components. Its job is to prevent fluid — whether hydraulic oil, coolant, or fuel — from passing the joint under pressure or during operation. In a single drum vibratory roller like the RS800 series, O-Rings appear throughout the hydraulic drive system, engine connections, and fluid circuits, where they hold pressure and keep contaminants out. When an O-Ring ages, hardens, or becomes compressed beyond its serviceable limit, it loses its ability to seal, resulting in fluid leaks, pressure loss, and potential damage to the components it was protecting. Replacing a worn O-Ring with the correct part — matching both diameter and cross-section — restores the seal to its original condition and prevents further fluid loss.
