Donaldson Diesel Exhaust Fluid Housings

A diesel exhaust fluid housing contains the filter that protects the DEF dosing system. It is designed for the fluid it holds: DEF is corrosive to some materials and crystallises where it is exposed to air, so housings and seals in this part of the system are specified accordingly.

Housings are matched to the dosing system and to the element they take. Search by Donaldson part number, or give us the engine or dosing system details.
