The Wacker Neuson Filler Cap is a genuine OEM filler cap designed for the RC110 and RC110P series ride-on compactors, including US Rops and US CAB configurations. As a direct OEM replacement, this cap is manufactured to the same standards as the original part that left the factory, ensuring a proper seal and correct fit every time. It covers the full RC110 and RC110P lineup, making it the go-to replacement whether you're running a standard, Rops, or cab-equipped machine. Confirm your model number before ordering to make sure is the right cap for your unit.
Key Features
- OEM-Grade Sealing Material — Manufactured to the same seal integrity specification as the original, preventing fluid contamination and pressure loss at the filler point.
- Drop-In Thread Compatibility — Threads directly onto the existing filler neck with no rework needed, matching the original cap's thread pitch and diameter exactly.
- Broad RC110 Series Coverage — Fits RC110 and RC110P compactors across standard, US Rops, and US CAB variants, covering a wide range of machine configurations under one part number.
- Contamination Protection — A properly seated filler cap keeps dirt, debris, and moisture out of the fluid reservoir — a worn or missing cap risks rapid fluid degradation and internal component damage.
- Fuel System Safety — A secure, correctly fitting cap is essential for preventing fuel or fluid spillage during operation, reducing the risk of fire hazard or environmental spillage on the worksite.
A filler cap seals the opening of a fluid reservoir — typically fuel or hydraulic fluid — on a piece of equipment. Its job is to keep the system closed while allowing access for filling and fluid level checks. When a filler cap is cracked, stripped, or missing, contaminants such as dirt and water can enter the reservoir, leading to accelerated wear on internal components and potential system failure. On a ride-on compactor like the RC110, maintaining a tight seal at every fluid access point is critical to keeping the machine running cleanly and safely under heavy daily use.
