The Wacker Neuson Sealing Ring is a genuine OEM component designed for the RD40-130 and RD45-140 series tandem rollers, including standard, C, O, DPF, and US variants. Sourced directly from Wacker Neuson, this sealing ring matches the exact material grade, dimensions, and compression characteristics of the original part — so it seats correctly and performs as intended from the moment it's installed. Compatible across a broad range of RD40-130 and RD45-140 configurations, the is the correct replacement whether you're servicing an older machine or a current DPF-compliant model.
Key Features
- OEM-Grade Seal Material — Manufactured to Wacker Neuson's original material and compression specifications, ensuring the ring forms a consistent, leak-free seal under operating conditions typical of vibratory tandem rollers.
- Drop-In Replacement — Matches the original sealing ring profile exactly, allowing straightforward installation without reworking surrounding components or mating surfaces.
- Broad RD Series Fitment — Confirmed fit across RD40-130 and RD45-140 families, covering standard, C, O, DPF, and US model variants across multiple serial number ranges.
- Prevents Fluid Loss and Contamination — A properly functioning sealing ring keeps fluids contained and external contaminants out; a worn or damaged seal can lead to fluid ingress, accelerated wear on internal components, and unplanned service intervals.
- Genuine OEM Part — Supplied as an authorized Wacker Neuson replacement, carrying the same part number used in the original assembly for straightforward parts verification.
A sealing ring creates a pressure-tight barrier between mating components, preventing fluid leakage and stopping dirt, water, or debris from entering sensitive internal assemblies. In vibratory tandem rollers like the RD40-130 and RD45-140 series, these seals are exposed to continuous vibration, heat cycling, and hydraulic pressure — conditions that gradually degrade seal material over time. When a sealing ring fails, fluid loss can affect hydraulic function or lubrication, and contamination can cause accelerated wear to the components it was protecting, making timely replacement essential to keeping the machine operating correctly.
