D638-002-02+B Filter Element

Product Overview

The D638-002-02+B filter element is a core consumable filtration component for heavy-duty diesel engines, widely applied in construction machinery and commercial heavy trucks. It efficiently filters fine dust, metal particles, carbon deposits and other harmful impurities in engine oil, fuel and intake air. This purification process effectively protects precision engine components, reduces internal friction and wear, and maintains stable engine operating performance. Adopting high-density multi-layer composite filter media, this filter element features uniform pore size, high filtration accuracy and large dirt holding capacity. It maintains stable filtering performance under high pressure, high temperature and long-term continuous heavy-load working conditions. Manufactured strictly in accordance with OEM dimensional and technical standards, the D638-002-02+B filter element achieves 100% dimensional interchangeability, serving as a perfect direct replacement for original filter elements for daily maintenance and engine overhaul.
