Weld Specialty Supply Corp. now distributes NitroFill™ nitrogen generators, along with high
pressure nitrogen gas cylinders, used to inflate tires. The military as well as commercial aircraft
are required to use nitrogen in their tires due to the extreme change in temperature at high
altitudes. When safety and performance count, you can count on NitroFill™. NitroFill™ has
developed a way to make 99.9% pure nitrogen available and affordable to everyone.

Why should I use Nitrogen instead of compressed air?

Nitrogen is a dry gas free of moisture that doesn't deteriorate rubber like the ”wet oxygen”
in compressed air. Nitrogen has a larger molecular structure and won't leak like oxygen.
Nitrogen also makes tires less susceptible to air loss as temperatures change. Oxygen
molecules are smaller than nitrogen and leak 3 to 4 times faster. Oxidation over time breaks
down tire rubber and then it loses elasticity, strength and leaks even more. Nitrogen being
dry reduces wheel corrosion and extends the tires usable life by up to 30%. Nitrogen
maintains proper tire pressure which reduces running temperatures. This increases tire life,
improves fuel economy and aids in the control of better braking and handling.

  • Improves fuel economy
  • Decreases false alarms and activation of Tire Pressure Monitoring Systems
  • Reduces running temperatures
  • Dramatically slows pressure loss from permeation
  • Reduces tire oxidation
  • Eliminates interior wheel corrosion
Our state-of-the-art equipment and procedures provide a verifiable concentration of pure
nitrogen. In addition to the benefits of nitrogen tire inflation we provide a comprehensive
dealer customer retention program and the NitroFill™ Auto Club. The NitroFill™ Auto Club
has all the benefits of other auto clubs with the addition of a tire repair and replacement
due to a road hazard at a more than competitive price.
