The Wacker Neuson Filler Cap is a genuine OEM component designed for the RC110 and RC110p series ride-on compactors, including ROPS and CAB configurations. Sourced directly from Wacker Neuson, this filler cap meets the exact specifications of the original part fitted at the factory.

When you need a direct, like-for-like replacement, the is the correct part for the job.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and thread specifications, ensuring a positive seal that prevents fluid contamination and loss.
- Direct Drop-In Replacement — Threads directly into the original filler port with no rework required, matching the original cap's dimensions and thread pitch exactly.
- Broad RC110 Series Coverage — Fits RC110 and RC110p compactors across standard, ROPS, and CAB configurations, including US-market variants.
- Contamination Protection — A properly seated filler cap keeps dirt, debris, and moisture out of the fluid reservoir, protecting internal components from premature wear.
- Fuel System Compliance — A correctly fitted OEM cap maintains proper venting and pressure balance in the filler system, preventing fuel or fluid loss during operation.
A filler cap seals the fluid reservoir fill point on the compactor, preventing fluid from escaping and stopping contaminants such as dirt and water from entering the system. On ride-on compactors like the RC110 series, a compromised or missing filler cap can lead to fluid contamination, accelerated component wear, or fluid loss that goes unnoticed until damage has already occurred. Replacing a cracked, damaged, or poorly sealing cap promptly is a simple step that protects the broader machine system.
