Wacker Neuson 5000043203 Lip Seal Ring

The Wacker Neuson is a genuine OEM Lip Seal Ring designed for BPU and DPU series reversible vibratory plate compactors. As a factory-sourced component, it meets the exact material and dimensional specifications set by Wacker Neuson for these machines — no guesswork on fit or compatibility. This part is confirmed to fit a wide range of BPU and DPU models, including the BPU 3545A, BPU 5045A, BPU 5545A, DPU 4045H, DPU 4545H, DPU 5045H, DPU 5545H, DPU 6055, DPU 6555H, and DPU 7060 series. When a seal fails, fluid leaks and contamination follow — replacing it with the correct OEM part restores proper sealing integrity and protects the surrounding components from damage.

Key Features

• OEM-Grade Sealing Material — Manufactured to Wacker Neuson's exact compound and compression specifications, ensuring the seal conforms correctly to mating surfaces and holds under the high-vibration demands of reversible plate compactor operation.
• Direct Drop-In Replacement — Engineered to the original profile and lip geometry, this seal installs in the same position as the factory part without modification to the housing or shaft.
• Broad BPU and DPU Fitment — Fits an extensive range of Wacker Neuson reversible vibratory plate compactors across the BPU 3545A / 4045A / 5045A / 5545A and DPU 4045 / 4545 / 5045 / 5545 / 6055 / 6555 / 7060 series.
• Protects Internal Components — A correctly seated lip seal prevents fluid loss and keeps contaminants out of the exciter housing, preserving bearing and gear integrity over the long service life of the compactor.
• Fluid Containment Compliance — Maintaining an intact seal is critical to preventing hydraulic or exciter fluid leaks that can create slip hazards and lead to regulatory non-compliance on managed job sites.

A lip seal ring creates a dynamic, low-friction barrier between rotating or reciprocating components and the outside environment. In a reversible vibratory plate compactor, this seal is responsible for retaining exciter housing fluid while keeping dirt, dust, and moisture from entering the assembly. When the lip wears, hardens, or becomes damaged, fluid seeps out and contaminants work their way in — accelerating wear on internal gears and bearings and ultimately leading to exciter failure. Replacing a worn lip seal ring promptly is one of the most cost-effective ways to protect the drivetrain of a high-cycle compaction machine.
