The Wacker Neuson is a genuine OEM O-Ring 91.67 X 3.53-70 Shore designed for the RS800, RSS800A, RT560, and RT820 series single drum vibratory rollers and vibratory trench rollers. As a direct OEM replacement, part is manufactured to the exact compound grade and dimensional tolerances required by Wacker Neuson for this application, ensuring a correct seal under operating pressures and temperatures. This O-ring fits multiple configurations across the RS800 and RT820 roller families, including the RT820HT and RS800V variants. Keeping a correctly rated O-ring in place is essential to maintaining system integrity and preventing fluid loss that can lead to unplanned service events.
Key Features
- 70 Shore Durometer Rating — The 70 Shore hardness specification balances flexibility and compression resistance, providing consistent sealing performance under hydraulic or fluid system pressures typical of compaction equipment.
- Exact OEM Dimensions — At 91.67 x 3.53 mm, this O-ring seats precisely into its groove without over-compression or under-fill, both of which can cause premature seal failure.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain, this component meets the same material and compound standards as the part originally installed at the factory.
- Broad RS800 and RT Series Fitment — Confirmed fitment across RS800, RS800A, RS800H, RS800V, RSS800A, RT560, RT820, and RT820HT models, covering a wide range of single drum rollers and vibratory trench rollers.
- Prevents Fluid Loss and System Contamination — A failed or worn O-ring at this specification can allow hydraulic fluid or coolant to bypass the seal, introducing contamination or causing pressure drop that compromises machine operation.
- Fluid System Integrity — Using the correct compound grade and size matters in hydraulic and fluid sealing applications; an incorrect O-ring can swell, shrink, or degrade when exposed to system fluids, creating a leak path over time.
An O-ring is a circular elastomeric seal that prevents fluid or gas from passing between two mating surfaces, such as a fitting, port, or housing. In roller and trench roller applications, O-rings are commonly used throughout the hydraulic system, drum drive circuits, and fluid reservoirs to maintain pressure and prevent contamination ingress. When an O-ring degrades, hardens, or takes a set over time, it loses its ability to conform to the mating surfaces, resulting in weeping or active leaks that can affect hydraulic performance and require immediate attention.
