Diesel Exhaust Fluid (DEF) Injector
Mack

The DEF injector is essential for delivering precise amounts of diesel exhaust fluid into the exhaust system to reduce emissions. Its high-pressure operation ensures proper atomization and distribution, which is critical for effective SCR (Selective Catalytic Reduction) system performance. Proper functioning of this injector helps meet stringent emissions standards while maintaining engine efficiency. Its durable design resists corrosion and thermal stresses, ensuring long-term reliability. Regular maintenance of the DEF injector prevents system failures and costly repairs. Source One Parts Center provides this component to support emission compliance and environmental responsibility in heavy-duty vehicles.
