Wacker Neuson 5000108801 O-Ring

The Wacker Neuson O-Ring is a genuine OEM sealing component designed for a broad range of Wacker Neuson compaction and pump equipment, including the RD7 and RD7H tandem roller series, DPU reversible vibratory plate compactors (DPU 2440H through DPU 6555H variants), DPS single-direction vibratory plates, and PT2H trash pumps. As a direct OEM part, is manufactured to the exact material and dimensional tolerances specified by Wacker Neuson, ensuring a proper seal every time. This O-Ring serves a wide cross-section of the Wacker Neuson lineup, making it a smart stocking item for dealers, rental fleets, and contractors running multiple machines. Confirm your model number against the fitment list before ordering to ensure full compatibility.

Key Features

• OEM-Matched Sealing Material — Manufactured to Wacker Neuson's exact compound specification, delivering the compression resistance and chemical compatibility required for hydraulic and fluid circuit applications in compaction and pump equipment.
• Drop-In Dimensional Accuracy — The 5000108801 seats into the original groove without stretching or shimming, restoring a leak-free interface exactly as the machine was built.
• Broad Cross-Series Fitment — Confirmed for RD7 and RD7H walk-behind tandem rollers, DPU 2440H–6555H reversible vibratory plate compactors, DPS 1850H and DPS 2050H single-direction plates, and PT2H centrifugal trash pumps.
• Leak Prevention Where It Counts — A failed or extruded O-Ring leads to fluid loss, pressure drop, and potential damage to surrounding hydraulic or pump components; replacing it promptly with the correct OEM part restores full system integrity.
• Fluid System Safety — Maintaining a proper seal in hydraulic and pump circuits prevents uncontrolled fluid loss that can create slip hazards and lead to unplanned equipment shutdowns on active worksites.

An O-Ring is a circular elastomeric seal that sits in a precision-machined groove between two mating surfaces, creating a pressure-tight barrier that prevents fluid or air from escaping the system. In compaction equipment like the RD7 tandem roller and DPU reversible plate series, O-Rings are found throughout hydraulic circuits, exciter housings, and fluid reservoirs, where maintaining correct pressure is essential for consistent compaction force. When an O-Ring degrades, cracks, or is extruded out of its groove, the resulting leak can cause a drop in hydraulic performance, contamination of surrounding components, and — if left unaddressed — accelerated wear across the entire circuit.
