The Wacker Neuson 5100031847 is a genuine OEM Valve Cap designed for the RD7Ye, RD7Yeh HRC, RD7Yehf HRC, RD7Yehfb HRC, RD7Yeh LRC, RD7Yehf LRC, RD7Yehfb LRC, and RD10Yehf LRC walk-behind tandem roller series. As a factory-sourced component, this Valve Cap is produced to the same specifications as the original part installed at the time of manufacture. Correct fitment across the full RD7 and RD10 tandem roller families is confirmed, covering both HRC and LRC configurations.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to original tolerances, ensuring the valve is properly sealed against contamination and pressure loss in the drum or fluid circuit.
- Direct Drop-In Replacement — Threads to the same valve stem spec as the original, requiring no adaptation to reinstall on compatible RD7 and RD10 tandem roller models.
- Broad RD7 and RD10 Coverage — Verified to fit RD7Ye, RD7Yeh HRC, RD7Yehf HRC, RD7Yehfb HRC, RD7Yeh LRC, RD7Yehf LRC, RD7Yehfb LRC, and RD10Yehf LRC configurations.
- Protects Valve Function — A properly seated valve cap keeps debris and moisture away from the valve core, preventing slow leaks that affect drum pressure and compaction consistency on asphalt and soil surfaces.
- Sourced from Wacker Neuson — Part number 5100031847 is an authorized Wacker Neuson OEM part, ensuring compatibility with your machine's original service documentation.
A valve cap serves as the first line of defense for the valve stem it protects, sealing out dirt, water, and debris that can cause the valve core to stick, corrode, or leak over time. On walk-behind tandem rollers like the RD7 and RD10 series, maintaining correct drum pressure is critical to achieving consistent compaction pass after pass — a missing or damaged valve cap can allow slow pressure loss that degrades compaction output without any obvious warning. Replacing a worn or lost valve cap with the correct OEM part, Wacker Neuson 5100031847, is a simple step that protects a much more costly component from premature failure.
