The Wacker Neuson O-Ring Seal is a genuine OEM component designed for the RD24-100 and RD27-120/RD28-120 series tandem rollers, covering standard, C, O, DPF, and US variants across multiple production generations. As a direct OEM replacement, this seal is manufactured to the exact material grade and dimensional tolerances specified for the original application, ensuring proper compression and sealing performance. Compatible fitment spans the full RD24-100 and RD28-120 series families, including.3-generation and DPF-equipped models, making it a reliable go-to part for both scheduled service and field repairs.
Key Features
- OEM-Grade Elastomer Construction — Manufactured to the original material specification for correct compression set and sealing integrity under operating pressures and temperatures typical of tandem roller hydraulic and fluid systems.
- Drop-In Dimensional Match — Sized to the exact cross-section and inside diameter of the original seal groove, allowing straightforward installation without reworking the mating surfaces.
- Broad Series Coverage — Fits RD24-100 and RD27-120/RD28-120 tandem rollers across standard, C, O, US, .3-generation, and DPF configurations, consolidating your parts inventory for a wide range of machines.
- Leak Prevention Where It Counts — A correctly seated O-Ring Seal maintains fluid containment in the system it serves; a degraded or incorrectly sized seal leads to fluid weeping, pressure loss, and accelerated wear on surrounding components.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5100024320 carries the full backing of the OEM supply chain with no substitution in material or geometry.
An O-Ring Seal creates a static or dynamic fluid-tight barrier between two mating surfaces or components within a machine's hydraulic, lubrication, or fluid circuit. It works by deforming slightly under compression to fill any microscopic gaps at the joint, preventing fluid from escaping under pressure. When an O-Ring Seal hardens, cracks, or loses its elasticity with age and heat cycles, the resulting leak can cause fluid loss, contamination of surrounding components, and eventual system failure — making timely replacement critical to keeping the roller operating correctly.
