Genuine Diesel Engine Parts Filter Head Adapter 4066190 For Cummins QSK45

This adapter is built from premium 316L stainless steel, delivering solid anti-corrosion performance under saltwater and high-sulfur fuel working conditions. Equipped with PTFE-lined brass manifold, it stably holds up to 150 PSI for QSK19/QSK38 engines. Its multi-port layout fits parallel filter setups well, and self-aligning O-rings cut mounting torque roughly 40% versus old models. It meets ISO 16949 & SAE J1939 standards, works with built-in sensors for pressure tracking, and boasts long service life on Komatsu PC8000 excavators, LNG tugs and Tier IV locomotive auxiliary units.
