The Wacker Neuson Piston Packing is a genuine OEM component designed for the DPU 100-70Les reversible vibratory plate compactor. Sourced directly from Wacker Neuson, this packing is manufactured to the exact material grade and dimensional tolerances specified for this machine. It drops in as a direct replacement, restoring the hydraulic integrity of the exciter or drive piston assembly without modification. If you're servicing a DPU 100-70Les that's showing signs of internal hydraulic leakage or compaction loss, this is the part to reach for.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's specified material grade, ensuring correct compression characteristics and long-term resistance to hydraulic fluid degradation.
- Direct Piston Assembly Replacement — Engineered to seat precisely within the piston bore of the DPU 100-70Les, restoring a leak-free seal without rework or shimming.
- Confirmed Fitment — Verified for the DPU 100-70Les reversible vibratory plate compactor; always cross-reference your machine's serial number before ordering.
- Restores Full Compaction Force — A worn or degraded piston packing allows hydraulic pressure to bypass the piston, reducing exciter output and leaving soil or aggregate undercompacted. This replacement brings output back to spec.
- Hydraulic System Integrity — Maintaining a sound piston seal prevents internal fluid bypass from escalating into broader hydraulic system damage, protecting pump life and overall drivetrain health.
The piston packing forms a critical dynamic seal within the hydraulic piston assembly of the DPU 100-70Les, keeping pressurized fluid on the correct side of the piston so that full force is transferred to drive the compaction mechanism. When the packing wears, cracks, or loses its compression set, hydraulic fluid slips past the seal, reducing effective pressure and causing a noticeable drop in plate force or erratic exciter behavior. Replacing the piston packing at the first sign of internal leakage is the most cost-effective way to restore consistent compaction performance and protect the surrounding hydraulic components from accelerated wear.
