D638-002-02 D9-220 Fuel Filter is the direct replacement spin-on filter you need for reliable diesel engine protection. Built tough, it features a heavy-duty metal canister and a precision-pleated media blend that traps contaminants down to the micron level, safeguarding your fuel injectors from wear. We've made it practical for the shop floor. It includes a standard water drain valve at the bottom for easy service. The gasket is designed to seal correctly on the first spin, saving time and preventing leaks. You'll find it offers consistent flow and optimal filtration capacity for the D9-220 application.

advantages
- High Filtration Efficiency for Engine Protection：We use high glass-fiber content glass fiber filter media (with 60%+ glass fiber ratio) that traps ≥99.5% of particles ≥5μm. This media also has a dirt-holding capacity of over 20g, so it doesn't clog quickly-keeping fuel clean to protect fuel injectors and the engine, and extending engine service life by up to 15%.
- Durable, Corrosion-Resistant Housing：The housing is made of Q235 galvanized carbon steel, formed via precision stamping to ensure uniform wall thickness (2.5mm ±0.1mm). We add an electrophoretic coating on the surface, which resists rust even in wet or dusty environments (like mining areas or rainy weather). It won't crack or deform under normal working pressure (0.3-0.6MPa).
- Leak-Proof Sealing to Maintain Fuel Pressure：It has a one-piece molded seal groove (no welded joints) that holds an NBR rubber seal. The seal fits tightly with the snap-fit interface, and we control the interface tolerance to ±0.1mm-this stops fuel leaks and keeps fuel pressure stable. You won't have issues like pressure drops that hurt engine performance.
