The Wacker Neuson is a genuine OEM O-Ring 47x2,5 designed for the RD7 and RD10 series double drum rollers, including RD7H, RD7Heh, RD7Yeh, RD7Af, RD7Hf, RD7Hehf, RD7Yehf, and RD10Yehf model variants. Sourced directly from Wacker Neuson, this is an exact replacement seal that meets the original equipment specification for your machine. The covers an extensive range of RD7 configurations — LRC and HRC variants, flush-drum and padfoot models — making it the right choice across the full roller lineup. Keep this seal on hand as a standard service item and avoid the risk of leaks that come with worn or incorrect o-rings.
Key Features
- OEM Seal Material and Sizing — Manufactured to the exact 47x2,5 mm dimensional spec with the correct elastomer compound to maintain compression and sealing integrity under hydraulic and vibratory operating conditions.
- Drop-In Installation — Matches the original groove dimensions on RD7 and RD10 series roller assemblies, seating correctly without trimming, stretching, or modification.
- Broad RD7 and RD10 Series Coverage — A single part number fits RD7H, RD7Heh, RD7Yeh LRC/HRC, RD7Hf, RD7Hehf, RD7Yehf LRC/HRC, RD7Af HRC, RD7Hfb, RD7Hehfb, RD7Yehfb LRC/HRC, RD7Afb HRC, and RD10Yehf LRC variants.
- Prevents Fluid Loss and Contamination — A correctly seated o-ring maintains system pressure and keeps moisture, dirt, and debris out of critical assemblies — a failed seal allows fluid ingress that can escalate into costly component damage.
- Genuine Wacker Neuson Part — Supplied as authentic OEM stock under part number 5100006912, ensuring the seal profile, hardness, and material grade match what left the factory originally.
An o-ring is a small but critical sealing component used throughout roller assemblies to prevent the escape of hydraulic fluid or lubricant and to block contamination from entering sensitive interfaces. On compaction equipment like the RD7 and RD10 series, these seals are exposed to constant vibration and pressure cycling, which gradually degrades the elastomer and causes the ring to lose its sealing force. When an o-ring fails, the result is typically a visible fluid leak, loss of hydraulic pressure, or accelerated wear on the components it was protecting — all of which point back to a seal that needs to be replaced promptly with a correctly sized, properly rated part.
