The Wacker Neuson Filler Cap is a genuine OEM filler cap designed for the RC110 and RC110P compactor series, including US ROPS and US CAB configurations. As a direct OEM part, it is manufactured to the same standards as the original component that left the factory, ensuring a proper seal and correct fitment every time. This cap is confirmed compatible across the full RC110 family — RC110, RC110P, RC110 US ROPS, RC110P US ROPS, RC110 US CAB, and RC110P US CAB — making it a reliable like-for-like replacement for worn or damaged units.
Key Features
- OEM Sealing Integrity — Manufactured to exact thread and sealing tolerances so the cap forms a proper pressure-tight closure, preventing fluid contamination and leaks.
- Drop-In Fitment — Threads directly into the original filler neck with no modification; designed as a like-for-like swap on all covered RC110 variants.
- Broad RC110 Family Coverage — Fits RC110, RC110P, RC110 US ROPS, RC110P US ROPS, RC110 US CAB, and RC110P US CAB compactors in a single part number.
- Fluid Protection Where It Counts — A correctly seated filler cap keeps dirt, debris, and moisture out of the fluid reservoir; a damaged or missing cap can lead to contamination and accelerated internal wear.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, carrying the full part number 5100034937 for verified accuracy before you order.
A filler cap seals the fluid reservoir opening on your compactor, keeping the fluid system closed to outside contaminants while allowing safe access for servicing and top-ups. When the cap is cracked, stripped, or missing its seal, dirt and moisture can enter the reservoir and degrade fluid quality, leading to premature wear on internal components. Replacing a faulty filler cap promptly is one of the simplest and most cost-effective ways to protect the longevity of your RC110 compactor's operating system.
