Wacker Neuson 5000018194 O-Ring

The Wacker Neuson O-Ring is a genuine OEM sealing component designed for the DPU, BPU, and APU reversible vibratory plate compactor series. As a direct factory replacement, this O-Ring meets the original material and dimensional specifications required to maintain a proper seal within the compactor's hydraulic or fluid circuit. It is compatible with an extensive range of models spanning the DPU 2440 through DPU 110L families, BPU 2440A through BPU 5545A variants, and the APU battery-powered reversible plate series. Whether you're servicing a compact jobsite unit or a high-output diesel reversible plate, part number is the correct factory-specified seal.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original material grade and dimensional tolerances, ensuring the correct compression and chemical resistance for this application.
• Drop-In Replacement — Matches the original O-Ring profile exactly, seating into the same groove or port as the factory-installed part with no reworking of the mating surfaces.
• Broad Reversible Plate Compactor Coverage — Confirmed fitment across DPU 2440–DPU 110L diesel models, BPU 2440A–BPU 5545A gasoline models, and APU battery-powered reversible plate variants.
• Prevents Fluid Loss and Contamination — A properly seated O-Ring keeps hydraulic or fluid circuits sealed; a worn or damaged seal allows leaks that can starve components of lubrication or pressure, leading to accelerated wear.
• Fuel and Hydraulic Fluid Compatibility — The OEM-specified material resists degradation from the oils and fluids used in Wacker Neuson reversible plate compactor systems, maintaining seal performance over repeated thermal cycles.

An O-Ring is a circular elastomeric seal installed at a joint, port, or housing interface to prevent fluid or air from escaping the system. In a reversible vibratory plate compactor, O-Rings are used throughout the hydraulic circuit that controls plate direction and vibration, as well as in the engine and exciter assembly fluid passages. When an O-Ring hardens, cracks, or is damaged during service, it loses its ability to maintain a pressure-tight seal — resulting in fluid leaks, loss of hydraulic function, or contamination of internal components. Replacing a worn O-Ring promptly with the correct OEM part restores proper system pressure and protects surrounding components from damage.
