The Wacker Neuson Filler Cap is a genuine OEM Filler Cap designed for the RC110 and RC110p series ride-on compactors, including ROPS and CAB variants. As a direct OEM part, it is built to the exact material and dimensional specifications used in original production, ensuring a correct, secure fit every time. This cap is compatible across the full RC110 and RC110p lineup, covering standard, US ROPS, and US CAB machine configurations.
Key Features
- OEM-Grade Sealing Material — Manufactured to the same material and tolerance specs as the original, ensuring a proper compression seal that resists fluid contamination and leakage.
- Direct Drop-In Replacement — Threads directly onto the original filler neck with no modifications to the machine — designed to seat and torque exactly as the factory part does.
- Broad RC110 Series Fitment — Covers RC110 and RC110p compactors across standard, US ROPS, US CAB, ROPS, and CAB configurations, making it the correct part for the full model range.
- Prevents Fluid Contamination — A properly sealing filler cap keeps moisture, dirt, and debris out of the fluid system, protecting internal components from premature wear and corrosion.
- Fuel System Integrity — A failed or missing filler cap can allow vapors to escape and contaminants to enter — using the correct OEM cap maintains a closed, compliant fuel system on your machine.
A filler cap seals the fluid filler opening on the machine, preventing fuel, hydraulic fluid, or oil from spilling and blocking contaminants such as dirt and water from entering the system. When a filler cap is cracked, missing, or no longer seals correctly, it can compromise fluid quality, create a fire or spill hazard, and lead to accelerated wear on internal components. Replacing a worn or damaged cap promptly is one of the simplest ways to protect the broader fluid system and keep the machine operating as intended.
