40mm DEF Cap
Diesel exhaust fluid (DEF) has become an essential part of a truck’s fuel system, as it aids in the selective catalytic reduction that improves the efficiency of fuel burn.
The systems, while relatively new, have become a hallmark due to federal regulations. That said, DEF has added another aspect of maintenance for trucks, as it’s expendable and leaves the system open for additional issues.
Those issues can at least partly spawn due to poor protection of the intake area, which you can secure by using a 40mm DEF cap. The cap is corrosion proof and weather resistant, and it includes a tether to keep it near the area without having to worry about losing it.
It will prevent spills, overflows and leaks, as the DEF cap fits Class 6 and 8 trucks, with the exception of Volvo and Mack. Its distinctive blue color will allow for quick identification and appropriate maintenance.
