The Wacker Neuson is a genuine OEM O-Ring 4.234 X.139 N674-70 designed for the RD7 series walk-behind tandem rollers, including the RD7H-ES, RD7H-S, and RD7 double drum vibratory roller variants. Sourced directly from Wacker Neuson, this seal is manufactured to the exact compound grade, cross-section, and inside diameter specified for these machines. Using the correct OEM part ensures a proper seal interface at the intended installation point, preventing fluid loss or contamination that an improperly sized substitute could introduce. If you're servicing an RD7H-ES EU, RD7H-S EU, or any RD7H configuration, part number is the factory-specified replacement.
Key Features
- Exact Compound and Geometry Match — N674-70 grade nitrile rubber at the specified 4.234" ID and .139" cross-section ensures the seal seats and compresses correctly in its groove without over- or under-compression.
- Genuine OEM Part — Supplied by Wacker Neuson to the same specification used in original assembly, so there is no guesswork about material compatibility or dimensional accuracy.
- Drop-In Replacement — Engineered to fit the existing groove geometry on RD7 series rollers without reworking the housing or adjacent components.
- Broad RD7 Series Coverage — Fits RD7H-ES, RD7H-S, RD7H-ES EU, RD7H-S EU, and RD7 double drum vibratory roller configurations, making it the correct choice across the RD7 product family.
- Leak Prevention Where It Counts — A failed or hardened O-ring in a tandem roller allows fluid ingress or loss at a critical sealing point, leading to accelerated wear or system contamination. Fresh sealing restores integrity at that interface.
An O-ring is a precision-molded elastomeric seal that sits in a machined groove between two mating surfaces, compressing to form a fluid- or pressure-tight barrier. In a walk-behind tandem roller like the RD7 series, O-rings appear throughout the hydraulic, exciter, and lubrication circuits — wherever two components must seal against each other under pressure or rotation. When an O-ring hardens, cracks, or takes a permanent set from heat cycling, it loses its ability to compress evenly, allowing fluid to bypass the seal face, which can result in hydraulic leaks, contamination of adjacent assemblies, or loss of exciter function that directly affects compaction output.
