The Wacker Neuson O-Ring is a genuine OEM sealing component designed for the DPU4545, DPU5545, DPU6055, and DPU6555 series reversible vibratory plate compactors. As a direct factory replacement, it restores proper sealing integrity across a broad range of DPU models including the DPU6555He, DPU6555Heh, DPU6555Hec, DPU5545Heh, DPU5545Hec, DPU4545Heh, DPU4545Hech, and DPU6055 variants. Sourced directly from Wacker Neuson, this O-Ring is manufactured to the exact material and dimensional specifications of the original part. It is the correct choice for technicians and operators looking to restore a fluid-tight seal without guesswork or improvisation.
Key Features
- OEM-Matched Sealing Material — Manufactured to the exact compound and durometer specification of the original, ensuring proper compression and a lasting fluid-tight seal in the DPU hydraulic or fluid circuit where it is installed.
- Drop-In Fitment Across DPU Families — Dimensionally identical to the factory original, this O-Ring seats correctly in its groove without modification, covering DPU4545, DPU5545, DPU6055, and DPU6555 series machines.
- Wide Model Coverage — Compatible with a broad range of DPU variants including He, Heh, Hec, Hech, Heap, Hesh, Hecsh, Hechzf configurations and their US-market equivalents.
- Prevents Fluid Loss and Internal Contamination — A properly seated O-Ring keeps hydraulic or fluid pressure contained within the system; a worn or degraded ring leads to leaks, pressure loss, and potential damage to surrounding components.
- Fluid System Integrity — Correct O-Ring specification is critical in pressurized circuits; using an undersized or incompatible ring risks bypass leakage that can compromise compaction force and machine operation.
An O-Ring is a circular elastomeric seal used throughout hydraulic and fluid systems to prevent leakage between mating components such as ports, housings, valves, and fittings. In reversible vibratory plate compactors like the DPU series, O-Rings maintain pressure integrity within the hydraulic drive circuit that controls plate direction and compaction force. When an O-Ring degrades — through heat cycling, chemical exposure, or simple wear — it loses its ability to compress and seal, resulting in fluid seepage, reduced system pressure, and inconsistent plate performance. Replacing a worn O-Ring promptly with the correct OEM part is one of the most cost-effective ways to keep a compactor's hydraulic system operating as intended.
