The Wacker Neuson is a genuine OEM O-Ring designed for the DPU4545, DPU5545, DPU6555, and DPU6055 series reversible vibratory plate compactors, as well as the RD10 and RD25 hydrostatic double drum vibratory rollers. Sourced directly from Wacker Neuson, this part matches the original specification installed at the factory, ensuring a correct seal every time. It fits an extensive range of DPU variants — including Heh, Hech, Heap, Hes, and US-market configurations — making it a versatile service part for fleets running multiple DPU models. Keep one on hand during hydraulic system service intervals to avoid repeat trips to the parts counter.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and dimensional specification, delivering the compression and chemical resistance required in hydraulic and fluid-system applications on heavy compaction equipment.
- Drop-In Replacement — Profiles and cross-section dimensions match the original seat geometry on DPU and RD series machines, seating cleanly without reworking ports or fittings.
- Broad DPU Series Coverage — Compatible with DPU4545, DPU5545, DPU6055, and DPU6555 reversible vibratory plate compactors across a wide range of regional and configuration variants, plus RD10 and RD25 tandem rollers.
- Prevents Fluid Loss and System Contamination — A compromised O-Ring allows hydraulic fluid to bypass its seal, leading to pressure loss, erratic compaction performance, and potential pump or motor damage. Replacing it promptly restores system integrity.
- Hydraulic System Safety — On reversible plate compactors and hydrostatic rollers, a failed O-Ring in a hydraulic circuit can cause unexpected directional control loss. Using the correct OEM-spec seal supports safe, predictable machine operation.
An O-Ring is a precision loop of elastomeric material used to create a fluid-tight seal between two mating components — typically within hydraulic circuits, pump housings, valve bodies, or fluid ports. On reversible vibratory plate compactors and hydrostatic tandem rollers like the DPU and RD series, O-Rings are critical to maintaining hydraulic pressure that drives compaction force and directional travel. When an O-Ring degrades, cracks, or becomes compressed beyond its service limit, it loses its ability to hold a seal — resulting in fluid leakage, pressure drop, and reduced or unpredictable machine output. Replacing a worn O-Ring at the correct service interval is one of the most cost-effective ways to protect the wider hydraulic system.
