Wacker Neuson 5000043203 Lip Seal Ring

The Wacker Neuson 5000043203 is a genuine OEM Lip Seal Ring designed for BPU and DPU series reversible vibratory plate compactors, covering an extensive range of models including the BPU 3545A, BPU 5045A, BPU 5545A, DPU 4045, DPU 4545, DPU 5045, DPU 5545, DPU 6055, DPU 6555, and DPU 7060 series. Sourced directly from Wacker Neuson, part number 5000043203 is manufactured to the same specification as the original component installed at the factory. This seal ring is confirmed across a broad range of BPU and DPU configurations, including gasoline-powered BPU models and diesel-powered DPU variants, ensuring you get the correct part for your specific compactor. Verifying your model number before ordering is always recommended given the wide range of configurations within these families.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and dimensional specification, delivering the compression and retention properties required for a dynamic sealing application in a vibratory compactor drivetrain.
• Direct-Fit Replacement — Engineered to seat identically to the original seal ring, allowing installation without machining, shimming, or adaptation of the housing bore.
• Broad BPU and DPU Compatibility — Confirmed fitment across BPU 3545A, BPU 5045A, BPU 5545A, and a wide range of DPU 4045, DPU 4545, DPU 5045, DPU 5545, DPU 6055, DPU 6555, and DPU 7060 series reversible vibratory plate compactors.
• Leak Prevention Under Vibration — A failed or worn lip seal allows fluid to escape from the exciter housing or drive assembly, leading to contamination, accelerated bearing wear, and compactor performance loss. A sound seal keeps fluids where they belong under continuous high-frequency vibration loads.
• Verified Wacker Neuson Part Number — Cross-referenced as 5000043203 across multiple BPU and DPU model variants, so you can order with confidence that this is the correct seal for your machine.

A lip seal ring forms a dynamic barrier between rotating or reciprocating shafts and their surrounding housings, preventing lubricating oil or grease from escaping while blocking contaminants such as dirt and moisture from entering. In a reversible vibratory plate compactor, this seal is subjected to constant high-frequency vibration and rotational stress, making material quality and dimensional accuracy critical. When a lip seal ring deteriorates or fails, fluid loss quickly leads to overheating, increased wear on internal components, and ultimately drivetrain damage that takes the compactor out of service.
