The Wacker Neuson O-Ring is a genuine OEM sealing component designed for DPU 100-70 and DPU 9070 reversible vibratory plate compactors. As a direct factory replacement, this O-Ring delivers the exact material compound, cross-section diameter, and compression characteristics required to maintain a leak-free seal under the hydraulic and mechanical demands of heavy-duty reversible plate operation. Sourced directly from Wacker Neuson, part is manufactured to the same standards as the original component installed at the factory.
Key Features
- Genuine OEM Sealing Material — Manufactured from the correct elastomer compound to withstand hydraulic fluid exposure, pressure cycling, and the vibration loads specific to DPU-series reversible plate compactors.
- Exact-Profile Replacement — Matches the original cross-section and inner diameter so it seats correctly in the machined groove without shimming, trimming, or adapting.
- Confirmed Fitment — Verified for the DPU 100-70 (100 kN, 70 cm/28 in) and DPU 9070 reversible vibratory plate compactors.
- Maintains System Integrity — A failed or deteriorated O-Ring allows fluid leakage that can starve hydraulic circuits and cause erratic or lost reversing function; replacing it promptly restores full directional control.
- Long-Term Compression Set Resistance — OEM-spec compound resists permanent deformation over repeated heat and pressure cycles, helping the seal maintain its load-bearing profile throughout its service life.
An O-Ring is a precision-molded loop of elastomer that forms a static or dynamic seal between two mating surfaces — typically within a hydraulic circuit, pump housing, or valve body. In a reversible vibratory plate compactor like the DPU 100-70 and DPU 9070, O-Rings contain hydraulic fluid under pressure and prevent contamination from entering sensitive components. When an O-Ring hardens, cracks, or loses its shape, it can no longer maintain a consistent seal, leading to fluid weeping, pressure loss, and ultimately compromised reversing performance or hydraulic failure. Replacing a worn O-Ring with the correct OEM part is one of the most cost-effective ways to protect the broader hydraulic system.
