Wacker Neuson 5100047191 Piston Packing

The Wacker Neuson Piston Packing is a genuine OEM piston packing designed for the DPU5247, DPU5260, DPU5275, DPU6260, and DPU6275 series vibratory plate compactors, as well as BPU5260 and BPU6275 series models. Sourced directly from Wacker Neuson, this is the same part fitted at the factory — ensuring an exact dimensional match and correct sealing performance. It covers a wide range of H, He, Heh, Hehp, Hehcb+, Hehcpb+, and related variants across the DPU and BPU product lines, making it the go-to replacement for operators running these machines. Confirm your full model designation and serial number before ordering to ensure this is the correct piston packing for your unit.

Key Features

• OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and dimensional specification, delivering the compression and wear resistance required for consistent hydraulic sealing in the exciter unit.
• Direct Drop-In Replacement — Matches the original piston packing profile exactly, so it installs into the exciter housing the same way the factory part does — no reworking of mating surfaces needed.
• Broad DPU and BPU Series Coverage — Fits DPU5247, DPU5260, DPU5275, DPU6260, and DPU6275 series plates along with BPU5260Ah and BPU6275Ah models, spanning H, He, Heh, Hehp, cb+, cpb+, and US variants.
• Sustained Compaction Force — A healthy piston packing maintains the hydraulic pressure needed to drive consistent vibratory output; a worn or failed packing causes loss of exciter pressure and reduced compaction performance.
• Genuine Wacker Neuson Part — Part number 5100047191 is an authorized OEM component, giving you full traceability back to the original design specification for this exciter assembly.

The piston packing is a sealing component located within the vibratory exciter unit of the plate compactor. It maintains hydraulic pressure around the piston, which is essential for generating the centrifugal force that drives the plate's compaction action. When the piston packing wears or fails, the exciter loses pressure, vibration output drops off, and the machine's ability to compact soil or asphalt is significantly reduced — often without any obvious external warning until compaction quality suffers. Replacing a worn piston packing at the first sign of pressure loss or reduced vibration restores the machine to full working output and prevents further damage to surrounding exciter components.
