Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional standards as the original, ensuring consistent sealing and a secure interface with the filler cap and tank opening.
- Direct Drop-In Replacement — Engineered to install in the original mounting position with no reworking of the surrounding tank or cap hardware.
- Confirmed Fitment for RC110 and RC110P — Verified compatibility with both the RC110 and RC110P roller models, so you can order with confidence.
- Maintains Fluid Integrity — A correctly seated filler neck prevents contamination from entering the fluid system and stops leaks caused by a deteriorated or cracked neck.
- Fuel System Safety — Replacing a damaged filler neck eliminates the risk of fuel or fluid escaping at the fill point, reducing fire and contamination hazards on the worksite.
The filler neck is the entry point through which fluid — typically fuel or water — is added to the machine's tank. It provides a sealed passage between the tank opening and the filler cap, preventing spillage, contamination, and pressure loss during operation. When the filler neck becomes cracked, warped, or corroded, it can allow debris into the tank, cause fluid leaks at the fill point, or prevent the cap from seating properly — any of which can interrupt operation or cause damage to downstream components.
