Def Tank Cover

Home | Applications | Def Tank Cover





Suburban Manufacturing Group has been developing and manufacturing covers and sleeves to protect components from all sorts of ambient conditions for over 40 years. Recently Python has been requested to help with a new issue. EPA emission requirements have pushed the Engine Manufacturers to integrate diesel exhaust fluid into their systems to help regulate particulate matter or black soot, and nitrogen oxides that can be emitted to atmosphere from diesel engines.

Due to engine bay and footprint constraints, locating the DEF tank can present heat or cold issues effecting the diesel exhaust fluid. Heat can cause acid conversion prior to injection into the SCR and cold can cause freezing prior to injection into the SCR.

Python has developed a cover with an integrated insulation to prevent temperature migration. The outer layer will protect the insulation from external ambient conditions making this cover a needed feature for OEMS.


  • Radiant lined for thermal protection
  • External heavy urethane coating preventing moisture/air penetration
  • Low profile assembly
  • Military-grade hook and loop closures for easy installs
