Wacker Neuson 5100057493 O-Ring 297.00 x 4.00

The Wacker Neuson is a genuine OEM O-Ring 297.00 x 4.00 designed for DPU5260, DPU5275, DPU6260, DPU6275, and BPU5260/BPU6275 series vibratory plate compactors. As a direct Wacker Neuson OEM part, the is manufactured to the exact material grade and dimensional tolerances specified for these machines, ensuring a proper seal every time. This O-Ring covers an extensive range of models across the DPU and BPU families, including hydraulic-drive, hand-guided, and combo-bin variants. Confirm your model number before ordering to ensure full compatibility with your specific machine configuration.

Key Features

• OEM-Spec Sealing Material — Manufactured to Wacker Neuson's specified elastomer compound and compression rating for this exact 297.00 x 4.00 cross-section, maintaining hydraulic integrity under operating pressures and temperatures.
• Exact Dimensional Fit — The 297.00 mm inner diameter and 4.00 mm cross-section match the machined groove dimensions in these compactor assemblies, seating cleanly without stretching or pinching during installation.
• Broad DPU and BPU Series Coverage — Compatible with a wide range of DPU5260, DPU5275, DPU6260, DPU6275, and BPU5260/BPU6275 models, including He, Heh, Hehcb+, Hehcpb+, and LOXAM-spec variants.
• Prevents Fluid Loss and Contamination — A fully seated, undamaged O-Ring keeps hydraulic fluid contained and stops contaminants from entering the system — a worn or cracked ring can cause fluid leaks that degrade plate compaction force and damage internal components.
• Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson's authorized parts supply chain, so you're receiving the same component that leaves the factory with new machines — not a generic substitute.

An O-Ring is a precision sealing element fitted into a machined groove to create a leak-free barrier between two mating surfaces or around a moving shaft or port. In vibratory plate compactors like the DPU and BPU series, O-Rings are used throughout the hydraulic and exciter systems to contain fluid pressure and prevent ingress of dirt and moisture. When an O-Ring degrades — through heat cycling, compression set, or physical damage — it loses its ability to maintain a seal, leading to fluid weeping, pressure loss, and ultimately reduced compaction performance or component failure if left unaddressed.
