Fuel Water Separator

4120L-10M/10MB is a highly efficient, large-capacity spin-on diesel fine filter (also known as a secondary filter). Its core function is to remove extremely fine particulate impurities and moisture from diesel fuel, providing the highest level of protection for high-pressure common rail fuel injection systems (such as those in electronically controlled engines). It is a critical component for ensuring the smooth operation and extending the service life of modern diesel engines.

The WK 1060 high-performance fuel filter uses a multi-layer deep filtration media to efficiently remove over 99% of tiny particulate impurities, moisture, and rust from fuel, providing comprehensive protection for your fuel system. By ensuring that the fuel entering the combustion chamber is exceptionally clean, it restores engine power and smoothness, optimizes combustion efficiency, saves costs, and extends its service life.
