Title:
FILTER-OIL CARTRIDGE (KU-W21ESO1510)
Description:
The Kubota FILTER – OIL CARTRIDGE (KU-W21ESO1510) is a full-flow engine oil filter designed to remove contaminants from the lubrication system. It continuously filters engine oil, capturing metal particles, combustion residues, and debris, which helps maintain clean oil circulation.
Moreover, it ensures that only properly filtered oil reaches critical engine components such as bearings, pistons, and valve trains. As a result, it reduces wear, improves lubrication efficiency, and extends engine life.
In addition, Kubota engineers this cartridge filter with high-quality filtration media and a durable housing. Therefore, it maintains consistent oil flow while providing reliable filtration even under high temperature and pressure conditions.
Model Fitment:
This oil filter is widely used across Kubota mini excavators and compact construction equipment, particularly those equipped with compatible diesel engines.
