This NRF Urea Hose (part code 706008) is engineered to meet the demanding requirements of modern diesel exhaust fluid (DEF) systems. It plays a crucial role in delivering AdBlue (also known as DEF) to the exhaust stream, where it is injected to reduce harmful nitrogen oxide (NOx) emissions. The hose is constructed from durable materials that resist degradation from DEF, temperature fluctuations, and under-hood environments. This ensures a long service life and consistent performance, preventing leaks and maintaining the integrity of your vehicle's selective catalytic reduction (SCR) system. Proper functioning of the urea system is essential for compliance with emissions regulations and for maintaining engine performance. The NRF Urea Hose is a direct fit replacement, designed for easy installation and reliable operation.
