Chloramine, also known as monochloramine, is an inorganic compound, typically found in water, that is used in various industries for disinfection and bleaching. It is also used in chemical synthesis, as a flame retardant, and as a preservative for wood.
When rubber is exposed to chloramine, it can cause chemical degradation, leading to a decrease in tensile strength and elasticity. The rubber can also become brittle, leading to physical degradation. Additionally, chloramine can cause discoloration of the rubber, making it appear yellow or brown.
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.
