The Wacker Neuson Filler Cap is a genuine OEM component designed for RC110 and RC110p series ride-on compactors, including ROPS and CAB configurations. As a factory-sourced part, it meets the exact material and dimensional specifications set by Wacker Neuson, ensuring a correct seal every time. This cap is confirmed to fit across the full RC110 and RC110p lineup, covering both standard and US-market variants. If your current filler cap is cracked, leaking, or no longer sealing properly, part number is the straight swap to restore proper operation.
Key Features
- OEM Seal Integrity — Manufactured to Wacker Neuson's exact material and thread specifications, ensuring the cap seats and seals correctly without weeping or loosening under vibration.
- Direct Drop-In Replacement — Threads directly into the original filler neck with no rework or adapter needed, matching the fitment of the cap it replaces.
- Broad RC110 Series Coverage — Fits RC110 and RC110p compactors across standard, US ROPS, US CAB, ROPS, and CAB variants, making it the right part for a wide range of configurations.
- Contamination Protection — A properly seating filler cap keeps dirt, debris, and moisture out of the fluid reservoir, protecting internal components from premature wear.
- Fuel System Safety — A failed or missing filler cap on a compactor can allow fuel or hydraulic fluid to escape, creating a spill and fire hazard on site; replacing it promptly keeps the machine operating safely.
A filler cap seals the opening of a fluid reservoir — typically the fuel tank or hydraulic system — preventing contaminants from entering and stopping fluid from splashing or evaporating during operation. On a ride-on compactor like the RC110, maintaining a tight seal is critical because these machines operate under continuous vibration that can work a worn or ill-fitting cap loose over time. A damaged or missing cap can lead to fluid loss, contamination of the system, and in the case of fuel, a serious fire risk.
