DEF Shield

True Brand® DEF SHIELD effectively removes harmful crystalline deposits from the diesel DEF and SCR system while preventing new deposits from forming. It reduces back pressure and optimizes injector spray patterns to improve overall system efficiency and helps lower DEF consumption as well as operational and repair costs.

  • Eliminates and prevents def deposits
  • Restores optimal def spray pattern
  • Reduces def consumption
  • Reduces back pressure
  • Improves overall system efficiency
  • Prevents costly repairs
  • Ash-free formula

Part# T2613: 24 per case / 6 oz

SKU: T2613 Category:

DEF (Diesel Exhaust Fluid) reduces nitrogen oxides (NOx) emissions in diesel engines through selective catalytic reduction (SCR). Crystallization in the DEF can occur under certain conditions, particularly at low temperatures, leading to clogging or damage to the DEF and SCR system components like injectors, pumps, and lines.

DEF SHIELD effectively removes these crystalline deposits in the diesel DEF and Selective Catalyst Reduction (SCR) system while preventing new deposits from forming.
