Key Features
- OEM Sealing Integrity — Manufactured to exact tolerance for a secure, leak-free seal — critical for maintaining correct fluid levels and preventing contamination in the filler system.
- Direct Drop-In Replacement — Threads directly into the original filler port with no rework or adaptation needed, matching the original cap's profile and thread specification.
- Broad RC110 Series Coverage — Fits RC110 and RC110p machines across multiple configurations, including standard, US ROPS, US CAB, ROPS, and CAB variants.
- Protects Fluid Systems from Contamination — A correctly seated filler cap keeps dirt, debris, and moisture out of the fluid reservoir, protecting internal components from accelerated wear.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, so you get the correct part the first time — verified by part number 5100034683 for the RC110 and RC110p platform.
The filler cap seals the fluid filler opening on the compactor, preventing contaminants such as dirt, dust, and moisture from entering the reservoir during operation and storage. A properly functioning cap maintains the integrity of the fluid system, which is essential for consistent machine performance and component longevity. When a filler cap is cracked, missing, or no longer sealing correctly, contamination can enter the system and cause premature wear or damage to internal components — making timely replacement an important part of routine maintenance.
