Oxidizer

OXIDIZER O023

A fluid that will combine with carbon to form carbon monoxide or carbon dioxide. Oxidizers attack all forms of carbon so that means they will attack anything black in color, and that included black O-rings.

There are many oxidizers used in industry, here are some of the most popular ones we see:

  • Aqua Regia (a combination of nitric and hydrochloric acid) used for dissolving metals.
  • Chloric acid ignites organic material on contact.
  • Chlorous acid, over 200 degrees Fahrenheit (100 C).
  • Ferric chloride used in sewage treatment, photography, medicine and feed additives.
  • Hot sulfuric acid, the most widely used industrial chemical.
  • Hydrofluoric acid used for etching, cleaning castings and fermentation.
  • Methyl Ethyl Ketone (MEK) a common solvent.
  • Nitric acid used in fertilizer, dyeing, explosives, drugs, etching and medicine.
  • Oleum used in the manufacture of detergents and explosives.
  • Perchloric Acid – 2N
  • Perchloric acid used in the manufacture of medicine, explosives, and esters.
  • Sodium hypochlorite, used in bleaching paper pulp, textiles, and tanning textiles.
  • Sulfur trioxide used to manufacture sulfuric acid.

Additionally look for any chemical whose name contains the word:

  • Chlorate
  • Nitrate
  • Perchlorate
  • Permanganate
  • Peroxide
