The Wacker Neuson O-Ring is a genuine OEM component designed for the BS50-4As, BS60-4As, BS70-4As, BS62-4Ab/28, BS65-4As, BS68-4Ab/28, BS72-4As, and related 4-stroke rammer series. As a factory-sourced part, it is manufactured to the exact material grade and dimensional specification required by Wacker Neuson for proper sealing in these machines. This O-Ring is a direct replacement, covering a broad range of BS-series rammer configurations including US, CN, and Sunbelt variants. Keeping a verified OEM seal in place helps maintain fluid integrity and protects internal components from contamination or pressure loss.
Key Features
- OEM Material Grade Sealing — Manufactured from the factory-specified elastomer compound to deliver the correct compression and chemical resistance for rammer operating conditions.
- Drop-In Replacement — Matches original dimensions exactly, seating into the same groove as the factory-installed part with no trimming or adaptation.
- Broad BS-Series Compatibility — Fits BS50-4As, BS60-4As, BS65-4As, BS68-4As, BS70-4As, BS72-4As, BS62-4Ab/28, BS68-4Ab/28, and multiple regional variants including US, CN, and Sunbelt configurations.
- Prevents Fluid Ingress and Leakage — A correctly seated O-Ring maintains the sealed boundary between components; a worn or cracked one allows fluid or contaminant migration that can accelerate internal wear.
- Genuine Wacker Neuson OEM Part — Sourced directly through Wacker Neuson's authorized parts supply chain under part number 5100049224, ensuring you receive the correct specification every time.
An O-Ring is a circular elastomeric seal used to close the gap between two mating surfaces or components, preventing the passage of fluids, gases, or contaminants. In a 4-stroke rammer, O-Rings are critical to maintaining pressure integrity within the engine and drive systems — a compromised seal can lead to oil leakage, loss of lubrication, and accelerated wear on surrounding parts. Replacing a degraded O-Ring promptly with the correct OEM part restores the sealed interface and keeps the rammer operating at the performance level it was built for.
