AMMONIUM NITRITE Resistant O-Rings and Seals
Ammonium nitrite is also known as nitrous acid ammonium salt, nitrosyl ammonium, and nitrosonium. It is a yellow-orange crystalline solid and is used as a catalyst and oxidant in various industrial processes such as printing, welding, and dyeing.
When rubber is exposed to ammonium nitrite, it can cause hardening, embrittlement, and cracking due to the corrosive nature of the chemical. The acidity of the chemical can also cause a decrease in the tensile strength and elasticity of the rubber. Additionally, the presence of ammonium nitrite can lead to discoloration, staining, and fading of the rubber material.
Buna-N (NBR, Nitrile, Buna)
Buna-N o-rings also referred to as NBR o-rings and Nitrile o-rings are the most widely used o-ring material in the word because of low cost, good mechanical performance with resistance to water, most basic oils, lubricants and some fuels, many pneumatic, hydraulic systems, and the default choice for basic applications. Buna-N o-rings are not recommended for exposure to sunlight, UV light, ozone and general outdoor weathering or hash chemicals, acids, keytones and many others.
