Key Features
- OEM Material Specification — Manufactured to the exact compound hardness and elasticity required for rammer service conditions, ensuring consistent compression and seal performance over time.
- Drop-In Replacement — Matches the original cross-section and diameter so it seats correctly in the existing groove without trimming or adaptation.
- Broad BS Series Coverage — Compatible with BS 45Y, BS 50-2, BS 500, BS 52Y, BS 60-2, BS 600, BS 65-V, BS 70-2, BS 700, and their oil-injected and S-suffix variants.
- Leak Prevention — A properly seated O-Ring keeps fuel, oil, or air contained within the circuit it seals; a cracked or compressed-out ring leads to leaks, pressure loss, and potential internal damage.
- Fuel System Integrity — Where this O-Ring is used in the fuel circuit, maintaining a correct seal prevents fuel seepage and reduces fire risk during operation.
An O-Ring is a loop of elastomeric material that forms a pressure-tight seal between two mating surfaces or components within an assembly. On a vibratory rammer like the Wacker Neuson BS series, O-Rings are used throughout the fuel system, carburetor, and engine assemblies to prevent leaks and maintain the correct operating pressures. When an O-Ring hardens, cracks, or loses its round profile from heat cycling and age, it can no longer hold a seal, leading to fluid or air leaks that cause hard starting, rough running, or visible fuel weeping. Replacing a worn O-Ring with the correct OEM part restores a clean, reliable seal and protects surrounding components from contamination or pressure loss.
