AQUA REGIA Resistant O-Rings and Seals
Aqua regia is a mixture of two strong acids, nitric acid and hydrochloric acid, and is commonly used in the recovery of gold and platinum. It is also used in etching, as a laboratory reagent, and as an industrial cleaner and disinfectant. Common types of failures when rubber is exposed to aqua regia include cracking and erosion of the rubber due to the highly corrosive nature of the mixture. Rubber can also become brittle and swell, leading to further cracking and wear. The rubber may also become discolored or suffer from accelerated aging.
