The Wacker Neuson Piston Packing is a genuine OEM component designed for BPU and DPU series reversible vibratory plate compactors. As a direct factory replacement, this piston packing maintains the hydraulic integrity of the exciter system, ensuring consistent compaction force is delivered through the plate. Fitment covers an extensive range of models including the BPU 3545A, BPU 4045A, BPU 5045A, BPU 5545A, DPU 4045H, DPU 4045Y, DPU 4545H, DPU 4545He, DPU 5045H, DPU 5045He, DPU 5545H, DPU 5545He, DPU 6055, DPU 6555H, DPU 6555He, DPU 6555Hec, and DPU 5545Hec. Sourced directly from Wacker Neuson, part number meets the same material and dimensional standards as the seal fitted at the factory.
Key Features
- Factory-Grade Seal Material — Manufactured to the same compound and dimensional spec as the original, ensuring full compression and sealing performance within the exciter piston bore.
- Direct Drop-In Replacement — Engineered to install in the same position as the factory piston packing with no reworking of the bore or adjacent components required.
- Broad BPU and DPU Compatibility — Fits a wide range of Wacker Neuson reversible vibratory plate compactors across the BPU 3545A–5545A and DPU 4045–6555 families, covering both gasoline and diesel variants.
- Sustained Exciter Output — A correctly seated piston packing holds hydraulic pressure inside the exciter, keeping vibration amplitude consistent and compaction force at rated levels across soil and aggregate applications.
- Hydraulic System Integrity — A worn or extruded piston packing allows internal bypass, causing loss of reversibility and erratic plate direction control — risks that a fresh OEM seal directly eliminates.
The piston packing is a precision sealing element located within the hydraulic exciter assembly of reversible vibratory plate compactors. It creates a pressure-tight barrier around the exciter piston, allowing hydraulic force to drive the piston in both directions — which is what gives a reversible plate its ability to move forward and backward on command. When the piston packing wears, hardens, or tears, hydraulic fluid bypasses the seal, causing the machine to lose reversibility, produce uneven vibration, or fail to maintain compaction output. Replacing the piston packing at the first sign of fluid loss or directional sluggishness restores full exciter function and protects the broader hydraulic circuit from contamination and accelerated wear.
