Urea Fill Guard, Aluminum - CPI FG4503-1-163

The CPI FG4503-1-163 Urea Fill Guard is a high-quality, cast aluminum housing specifically designed for the secure and protected refilling of Diesel Exhaust Fluid (DEF) tanks in emergency vehicles and ambulances. As modern diesel engines utilize Selective Catalytic Reduction (SCR) systems to reduce Nitrogen Oxide (NOx) emissions, maintaining a clean and protected DEF fill point is essential to prevent contamination and ensure the vehicle remains emissions-compliant. This durable, 45-degree angled housing provides a robust interface for the filler neck, safeguarding against the rigors of heavy-duty daily use.
