The Wacker Neuson O-Ring Seal is a genuine OEM component designed for the RD40-130, RD45-140, and RC110 series tandem vibratory rollers. As a factory-sourced part, this O-Ring Seal meets the exact material and dimensional standards set by Wacker Neuson, ensuring a proper seal wherever it is installed. Compatible across multiple configurations including ROPS and CAB variants of the RC110 and RC110p, this seal covers a broad range of jobsite machines. When a seal in this system begins to degrade, fluid leaks and pressure loss follow quickly — making timely replacement with the correct OEM part essential.
Key Features
- OEM-Grade Seal Material — Manufactured to Wacker Neuson's specified elastomer compound and compression tolerances, delivering consistent sealing performance under operating pressure and temperature cycles.
- Drop-In Replacement — Matches the original groove dimensions exactly, seating cleanly without stretching, trimming, or modification during installation.
- Broad Model Coverage — Fits RD40-130, RD45-140 (including .3 and c.3 variants), and RC110 / RC110p series rollers in both ROPS and CAB configurations.
- Prevents Fluid Loss and Pressure Drop — A correctly seated O-Ring Seal maintains system integrity, keeping hydraulic or fluid circuits operating at designed pressure and preventing contamination ingress.
- Genuine Wacker Neuson Part — Sourced directly from the manufacturer, so the part number, dimensions, and material grade are fully traceable to the original design specification.
An O-Ring Seal creates a compression-based barrier between mating surfaces or around a shaft, preventing fluid — whether hydraulic oil, coolant, or lubricant — from leaking out of a circuit or allowing contaminants to enter. On compact tandem rollers like the RD and RC series, these seals are critical to maintaining the integrity of hydraulic and lubrication systems that power the drum vibration and drive functions. When an O-Ring degrades through heat cycling, age, or mechanical wear, the resulting leak can cause pressure loss, accelerated component wear, and eventual system failure if left unaddressed.
