The Wacker Neuson is a genuine OEM O-Ring 21 X 6-70 Shore designed for the BS65-V, BS650, and BS65Y series variable speed vibratory rammers. As a direct Wacker Neuson OEM part, the is manufactured to the exact material grade and dimensional specification required for proper sealing performance in these machines. This O-Ring is confirmed to fit multiple BS65 configurations, including EU-spec and BG Bau approved variants with the 280 mm/11 in shoe. Having the correct replacement seal on hand keeps your rammer serviceable and ready for the next compaction job.
Key Features
- 70 Shore Hardness, OEM Material Grade — The 70 Shore durometer rating matches the compression and elasticity requirements of the original seal, ensuring consistent seating and resistance to the operating temperatures and fluids found in BS-series rammers.
- Exact 21 mm Dimensional Spec — Sized to the original groove dimensions so the ring seats fully and compresses evenly without pinching, rolling, or leaking at installation.
- Broad BS65 Series Coverage — Fits BS65-V, BS650, and BS65Y variable speed rammers across multiple machine configurations, including 280 mm/11 in shoe variants and BG Bau approved units.
- Prevents Fluid Loss and Contamination — A worn or cracked O-ring allows fluid to bypass the seal, leading to leaks, contamination of adjacent components, and loss of operating pressure or lubrication where it matters most.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, this seal carries the same part number and specification as the component installed at the factory, removing any guesswork about material compatibility.
An O-ring is a precision loop seal used to close the gap between two mating surfaces, preventing the passage of fluids or gases under pressure. In a vibratory rammer like the BS65 series, O-rings are critical at fuel system connections, crankcase covers, and other sealed interfaces where even a minor leak can affect engine performance or allow contaminants to enter. When an O-ring hardens, cracks, or loses its compression set over time, it can no longer maintain a reliable seal, resulting in leaks, reduced pressure, or accelerated wear to surrounding components.
