With the new Tier 4 Final regulations now in full effect, it is time to face the reality that today’s equipment is in no way like your father’s equipment. In fact, it is even different than the last piece of off-road equipment you purchased. All of your 75 HP and up diesel powered equipment now uses Diesel Exhaust Fluid (DEF).

Keeping the selective catalytic reduction (SCR) systems free of contamination is a priority because any contamination of the SCR can jeopardize the system’s sensitive (and expensive) catalyst.

The DEFBooty is a protective cover that:

  • Protects the DEF cap and surrounding area from dust, dirt and debris of any kind
  • Maintains a clean area under the DEFBooty to prevent additional contamination from falling in the DEF tank (manufacturers suggest wiping off the DEF cap and surrounding areas prior to each refill of the tank)
  • Easily identifies the DEF tank from the other tanks on off road equipment (such as diesel and hydraulic tanks)
  • Provides an economical and effective solution that installs in seconds

The DEFBooty can be installed over the filler cap for the SCR system’s diesel exhaust fluid (DEF) tank and is secured with an attached elastic band to form a cover and apron over the cap and adjacent area. DEFBooty can be ordered online at www.defbooty.com.
