The Wacker Neuson 5100025873 Filler Cap is a genuine OEM component designed for the RC50, RC70, and RC110 series single-drum soil compactors. As a direct OEM replacement, this filler cap is manufactured to the same standards as the original part, ensuring a proper seal and correct fitment on your machine. Compatibility spans the full RC series lineup, including smooth-drum and padfoot variants, cab and ROPS configurations, and US-market models. Verify your machine's part number before ordering to confirm this cap is the correct match for your specific unit.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to the original specification, this filler cap delivers the same compression seal as the factory-installed component, preventing contamination and fluid loss.
- Drop-In Replacement — Threads directly onto the original fill port with no modification; matches the OEM cap's thread pitch and diameter for a secure, tool-assisted installation.
- Broad RC Series Coverage — Fits RC50, RC50p, RC70, RC70p, RC70vo, RC110, and RC110p models across standard, ROPS, CAB, and US-market configurations.
- Contamination Control — A properly seated filler cap keeps dirt, debris, and moisture out of the fluid system, protecting internal components from accelerated wear and costly damage.
- Fuel and Fluid System Safety — A failed or missing filler cap creates a spill and fire hazard on an operating machine; replacing a worn cap promptly is an important safety and compliance measure for fuel and hydraulic fill points.
A filler cap seals the fill port on a fluid reservoir — whether fuel, hydraulic, or coolant — preventing contaminants such as dirt, water, and debris from entering the system during operation and refueling. On heavy compaction equipment like the RC series single-drum soil compactors, maintaining a clean, sealed fluid system is critical to protecting pumps, valves, and other precision internal components. When a filler cap cracks, loses its seal, or goes missing entirely, it exposes the fluid system to ingestion of abrasive particles that accelerate internal wear and can lead to component failure.
