Wacker Neuson 5000087496 O-Ring .101 X 1/16 70Sh Buna

The Wacker Neuson is a genuine OEM O-Ring.101 X 1/16 70Sh Buna designed for the BS-series vibratory rammer lineup, including BS500, BS52Y, BS60Y, BS600, BS650, BS700, and their oil-injected variants. As a factory-sourced component, part number is manufactured to the exact material grade and dimensional tolerances specified for these machines. This seal is compatible across a wide range of BS-series configurations, including standard, high-altitude, and oil-injected rammer models. Keeping this O-ring in good condition is essential to maintaining proper fluid containment and preventing contamination in the rammer's internal systems.

Key Features

• 70-Durometer Buna-N Material — The 70Sh Buna-N compound delivers the compression resilience and chemical resistance required to seal fuel and oil system interfaces in gasoline vibratory rammers.
• Exact .101 X 1/16 Cross-Section Dimensions — Manufactured to the precise cross-section called out in the Wacker Neuson parts diagram, ensuring correct groove seating without gap or over-compression.
• Genuine OEM Sourcing — Supplied directly through the Wacker Neuson OEM parts network, confirming material specification and dimensional accuracy are consistent with the original installed part.
• Broad BS-Series Rammer Coverage — Fits BS500, BS52Y, BS60Y, BS600, BS650, and BS700 models, including standard, high-altitude, and oil-injected variants across multiple serial number ranges.
• Prevents Leaks That Lead to Internal Contamination — A degraded or improperly sized O-ring allows fluid ingress or loss at sealed junctions, which can lead to accelerated internal wear and unplanned service intervals on the rammer.

An O-ring is a circular elastomeric seal seated in a machined groove to prevent fluid or air from passing between two mated surfaces. In a vibratory rammer, O-rings are used at critical junctions in the fuel, oil, and air systems to maintain pressure integrity and keep contaminants out of precision-fit components. When an O-ring hardens, cracks, or deforms from age or heat exposure, it loses its ability to form a reliable seal — resulting in leaks, pressure loss, or contamination that can cause broader mechanical damage if left unaddressed. Replacing a worn O-ring with the correct OEM-specified part, such as Wacker Neuson 5000087496, restores the original sealing performance and protects the surrounding components.
