Wacker Neuson 5004101560 O-Ring

The Wacker Neuson O-Ring is a genuine OEM sealing component designed for a wide range of Wacker Neuson compaction equipment, including DPU reversible vibratory plate compactors, RD tandem rollers, and the RS800H single drum vibratory roller. As a factory-sourced part, it is manufactured to the exact material grade and dimensional tolerances required by the original design, ensuring a proper seal in hydraulic and fluid-carrying systems across all covered models. Confirm your model number before ordering — this O-Ring spans an extensive fitment list that includes DPU 2430F, DPU 4045H, DPU 5045H, DPU 6055, DPU 5260, DPU 5275, DPU 6260, DPU 6275, RD10, RD25, and RS800H variants. Sourcing the correct OEM O-Ring at the first sign of leakage is the fastest way to restore full hydraulic integrity and get your equipment back to work.

Key Features

• OEM-Matched Sealing Material — Manufactured to the exact compound specification required for hydraulic and fluid systems in Wacker Neuson compaction equipment, ensuring correct compression and seal integrity under operating pressures.
• Drop-In Replacement — Dimensionally identical to the original, this O-Ring seats directly into its groove without trimming, stretching, or adapting — no improvised substitutes that risk premature failure.
• Broad Compaction Equipment Coverage — Fits DPU-series reversible vibratory plate compactors (2430F through 6275 variants), RD10 and RD25 tandem rollers, and the RS800H single drum roller, covering both diesel and hydrostatic drivetrain configurations.
• Preserves Hydraulic System Integrity — A failed or worn O-Ring allows fluid to bypass the seal, causing pressure loss, external leaks, and accelerated wear on surrounding hydraulic components. Replacing it promptly keeps the system pressure-tight and operating as designed.
• Fluid-System Safety Compliance — Hydraulic fluid leaks at worn O-Ring points can create slip hazards and lead to uncontrolled machine behavior. Using the correct OEM-spec seal supports safe operation and helps meet equipment maintenance standards on regulated jobsites.

An O-Ring is a circular elastomeric seal fitted into a machined groove between two mating surfaces — such as a hydraulic fitting, valve body, or pump housing — where it compresses slightly to block fluid from escaping. In hydraulic-drive compaction equipment like reversible vibratory plates and tandem rollers, O-Rings are used throughout the hydraulic circuit to maintain system pressure and prevent internal or external fluid leaks. When an O-Ring degrades — through heat cycling, chemical exposure, or simple age — it loses its elasticity, flattens, or cracks, allowing fluid to bypass the seal. The result is typically visible leakage, a drop in hydraulic pressure, and reduced drive or vibration performance that will worsen until the seal is replaced.
