Key Features
- Exact OEM Material Specification — Manufactured to Wacker Neuson's specified elastomer compound, delivering the correct compression and chemical resistance required for this sealing application.
- Drop-In Replacement — Dimensioned to seat directly into the original groove without trimming or adapting, maintaining the integrity of the sealed joint on installation.
- Broad RD-Series Compatibility — Fits RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 tandem rollers across standard, open-drum, combination, and US-market variants.
- Leak-Free Operation — A properly seated O-Ring Seal prevents fluid intrusion or loss at the sealed interface, keeping the associated system operating at correct pressure and flow.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, so the part number, geometry, and material grade are verified against the original equipment specification.
An O-Ring Seal is a precision-formed elastomeric ring that creates a fluid- or air-tight barrier between two mating components, preventing leaks at joints, fittings, or housings within the machine's hydraulic, lubrication, or fluid-handling circuits. On RD-series tandem rollers, maintaining an effective seal is critical to sustaining hydraulic pressure and protecting internal components from contamination. When an O-Ring Seal deteriorates, cracks, or takes a compression set, it can allow fluid to bypass the sealed joint, leading to pressure loss, external leakage, and accelerated wear on the surrounding components it was designed to protect.
