NITRIC ACID, 3M TO 158?F Resistant O-Rings and Seals
Nitric Acid, also known as aqua fortis and spirit of niter, is a highly corrosive and oxidizing mineral acid. It is widely used in the chemical, pharmaceutical, and metalworking industries, as well as for the production of fertilizers, explosives, and dyes.
When rubber is exposed to nitric acid, the chemical can cause swelling, hardening, and cracking of the material. As nitric acid is highly corrosive, this can lead to loss of elasticity and eventual failure of the rubber seal. Additionally, certain rubber types are more prone to degradation from nitric acid than others, such as natural rubber, which is particularly sensitive to the acid.
