Wacker Neuson 5000013186 Seal Ring 12 X 15.5

The Wacker Neuson is a genuine OEM Seal Ring 12 X 15.5 designed for a wide range of Wacker Neuson RD-series tandem rollers and DPU-series reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this seal ring matches the exact material grade and dimensional tolerances of the original component. It fits across the RD7, RD10, RD15, and RD25 walk-behind tandem roller families, as well as DPU 2440H, DPU 2870, DPU 2950, DPU 2960, DPU 2970, DPU 4045H, DPU 4545H, DPU 5045H, DPU 5545H, DPU 6055, and DPU 6555H series reversible vibratory plates. Always verify your model and machine number before ordering to confirm fitment.

Key Features

• OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original compression and material specifications, ensuring the seal forms a consistent, leak-free barrier under operating pressures.
• Exact Dimensional Match — The 12 x 15.5 mm ring profile drops directly into the original seat without reworking or adapting the bore, maintaining proper sealing surface contact.
• Broad Cross-Family Fitment — Covers RD7, RD10, RD15, and RD25 tandem rollers alongside multiple DPU 4000–6500 series reversible vibratory plate compactors — one part number for a wide service inventory.
• Prevents Fluid Loss and Contamination — A correctly seated seal ring keeps hydraulic fluid or lubricant contained and blocks ingress of dirt and moisture, protecting downstream hydraulic and drive components.
• Genuine Wacker Neuson OEM Part — Part number 5000013186 is a factory-original component, giving you full confidence in dimensional accuracy and material compliance for professional service work.

A seal ring is a small but critical sealing element used at fluid connections, ports, and housing interfaces throughout hydraulic systems and lubricated assemblies. Its job is to prevent fluid from leaking past threaded fittings or mating faces while simultaneously stopping contaminants from entering the system. When a seal ring deteriorates — through compression set, heat cycling, or chemical degradation — it can allow hydraulic fluid to weep from connections, leading to pressure loss, erratic drive or vibration performance, and potential damage to pumps and motors. Replacing a worn seal ring with the correct OEM-spec part restores the integrity of the fluid circuit and keeps the machine performing as intended.
