Nitrous Oxide (N2O)


  • Colorless Liquid
  • Slightly sweet in odor
  • Non-flammable


It is chiefly as an inhalation anesthetic
As a dispersing agent in cream whippers

Enhances engine performance (for RACING)


    Nitrous Oxide is generally prepared by heating very pure ammonium nitrate to 200 oC in aluminum retorts.

Nitrous Oxide is non-corrosive and may be used with common structural metals provided the equipment is designed to withstand process pressure


- Compressed gas is commonly packed and shipped as a high pressure gas in seamless, steel cylinders constructed to Interstate Commerce Commission specifications 3A or 3AA and having a nominal capacities such as 80, 122, 150, 244, and 300 cu. ft. of gaseous nitrous oxide.

- Equipped with safety relief devices which consist of a frangible disc designed to burst under excessive pressure, a core of fusible metal with a low melting point designed to melt and release the gas in case of fire.

Note:  At normal pressure, the cylinder pressure ranges from 1100 psig to 1150 psig.


- For gas withdraw use cylinder upright
- Nitrous Oxide presents a lower temperature hazard and should not be allowed to contact skin or clothing
- Check local SUGECO branch for information on state legislation for use of Engine Boosting Grade
