Wacker Neuson 5100033181 O-Ring

The Wacker Neuson 5100033181 is a genuine OEM O-Ring designed for the BS50-2, BS50-2plus, BS60-2, BS60-2plus, BS62-2, BS68-2, and BS70-2 series gasoline vibratory rammers. Sourced directly from Wacker Neuson, this part meets the exact material and dimensional specifications of the original component installed at the factory. It fits a wide range of BS-series rammer configurations, including standard, plus, and lb variants across multiple stroke sizes. If your rammer is showing signs of fluid seepage or air leakage, the 5100033181 O-Ring is a direct path back to proper sealed operation.

Key Features

• Genuine OEM Sealing Material — Manufactured to the precise compound hardness and cross-section profile required for BS-series rammer service conditions, ensuring correct compression and seal integrity.
• Drop-In Replacement — Matches the original O-Ring dimensions exactly, seating into the same groove without modification to the housing or mating surfaces.
• Broad BS-Series Compatibility — Fits BS50-2, BS50-2plus, BS60-2, BS60-2plus, BS62-2, BS68-2, and BS70-2 rammer models, covering a wide range of stroke sizes and regional configurations.
• Leak Prevention — A properly seated O-Ring maintains the pressure differential and fluid containment that keep the rammer's internal systems functioning at full output; a degraded seal leads to loss of performance and potential internal damage.
• Fuel and Fluid System Integrity — Used in fuel or oil circuit applications, a correctly specified O-Ring prevents hazardous leaks, supporting safe rammer operation on the worksite.

An O-Ring is a precision-molded loop of elastomeric material that creates a static or dynamic seal between two mating components, preventing the passage of fluids or gases under pressure. In a gasoline vibratory rammer like the BS-series, O-Rings are found throughout the fuel system, oil circuits, and internal assemblies where leak-free connections are critical to consistent compaction performance. When an O-Ring ages, hardens, or is damaged during service, the resulting leak can lead to fuel contamination, oil loss, or pressure drop — all of which degrade rammer output and can cause accelerated wear to surrounding components.
