Description
Overview:
This non-genuine fuel cap is a direct replacement for the diesel tank cap used on Kubota compact machines, including the KX040-4 and KX057-4 mini excavators. It is designed to replace OEM reference RD411-51122 and provides a secure, screw-on closure for the fuel tank. Built from fuel‐resistant polymer with an integrated sealing gasket, it helps prevent leaks and keeps dirt, dust, and water out of the tank. The cap is made for day‐to‐day site use and fits the Kubota neck pattern used across selected KX, U and SVL series models. It installs by hand with no tools, offering a reliable seal that stands up to vibration, weather and fuel exposure, so your machine stays protected and ready for work.
Key Features:
- Non-genuine replacement matching OEM No. RD411-51122
- Fuel-resistant polymer body with integrated sealing gasket
- Secure screw-on design to minimise leaks and contamination
- Precise fit for the Kubota tank neck used on listed models
- Withstands vibration, weather and diesel exposure on site
- Tool-free fitting and removal for quick maintenance
- Helps maintain proper tank closure during transport and storage
- Practical, cost-effective alternative to OEM components
- Smooth outer profile for a firm, glove-friendly grip
- Suitable for routine servicing or replacing lost/damaged caps
Typical Applications:
Used to replace worn, damaged or missing fuel caps on Kubota compact excavators and track loaders. Helps prevent spills during refuelling and movement around site, reduces the risk of water or debris entering the tank, and supports reliable engine operation by maintaining a clean fuel supply. Ideal for routine maintenance, fleet repairs and keeping spare caps on hand to minimise downtime.
