The Wacker Neuson Filler Cap is a genuine OEM component designed for the RC110 and RC110p series compactors, including both US Rops and US CAB configurations. As a direct OEM replacement, this filler cap is manufactured to the same specification as the original part, ensuring a proper seal and fit on your machine. It covers the RC110 US Rops, RC110p US Rops, RC110 US CAB, and RC110p US CAB models, making it the correct choice across the full RC110 range. When it's time to service your compactor, using the right part the first time keeps the job moving.
Key Features
- OEM Sealing Integrity — Manufactured to the original sealing specification, this filler cap maintains the correct pressure and fluid containment characteristics required for compactor service points.
- Drop-In Replacement — Matches the original thread pattern and cap profile for a straightforward swap with no fitting or adapting needed.
- Full RC110 Series Coverage — Compatible with RC110 and RC110p compactors in both US Rops and US CAB configurations, covering the complete RC110 model family.
- Protects Fluid Cleanliness — A properly sealing filler cap prevents contamination from entering the fluid reservoir; a cracked or missing cap can introduce debris and moisture that degrades fluid and accelerates internal wear.
- Fuel and Fluid System Safety — A correctly seated filler cap is essential for preventing leaks and spillage at the fill point, reducing fire and contamination risk during refueling or fluid service.
A filler cap seals the opening used to add fuel or fluid to a reservoir on the machine. Its primary job is to keep contaminants — dirt, dust, and moisture — out of the fluid system while also preventing spillage during operation and transport. When a filler cap is cracked, warped, or missing its seal, it creates an entry point for debris that can contaminate the fluid and cause damage to pumps, injectors, or other internal components downstream. Replacing a worn or damaged filler cap promptly is a low-cost step that protects far more expensive machine components.
