The Wacker Neuson 5100012110 is a genuine OEM O-Ring Seal designed for the RD-series tandem roller lineup, covering RD24, RD27, RD28, RD40, and RD45 models across standard, combination, oscillation, and DPF configurations. As a direct Wacker Neuson OEM part, the 5100012110 is produced to the same tolerances and material specifications as the original component installed at the factory. This seal services an extensive range of variants including US-market,.3-generation, and DPF-equipped machines, making it a single-source solution for fleets running multiple RD-series rollers. Confirm your model number against the fitment list before ordering to ensure correct application.
Key Features
- OEM-Grade Elastomer Material — Manufactured to Wacker Neuson's original compound and durometer specifications, ensuring the seal compresses and seats correctly under operating pressures without cracking or extruding prematurely.
- Drop-In Groove Fit — Dimensioned to match the original O-ring groove geometry exactly, so it seats fully without pinching, twisting, or requiring groove modification during installation.
- Broad RD-Series Coverage — Fits RD24, RD27, RD28, RD40, and RD45 tandem rollers across standard, oscillation, combination, DPF, .3-generation, and US-market variants — one part number for a wide fleet.
- Leak Prevention Where It Counts — A correctly seated O-ring maintains system pressure and prevents fluid ingress or egress at the sealing interface; a degraded seal leads to fluid loss, contamination, and accelerated wear of surrounding components.
- Fluid System Integrity — On hydraulic or fluid-carrying circuits, a compromised seal can allow hydraulic fluid loss or water ingress that affects roller drive and vibration system performance — replacing it at the first sign of seepage protects the wider system.
An O-ring seal creates a pressure-tight barrier at a joint, port, or housing interface by compressing against two mating surfaces to prevent fluid or gas from passing through. In a tandem roller like the RD-series, O-rings appear throughout the hydraulic drive, vibration, and water-sprinkling systems, where maintaining sealed circuits is essential to consistent drum speed, vibration frequency, and operational control. When an O-ring ages, hardens, or takes a compression set, it loses its ability to fill the groove completely, allowing leaks that can cause pressure loss, system contamination, or unplanned downtime on the asphalt or soil compaction pass.
