Hydrogen chloride (also known as hydrochloric acid or hydrogen monochloride) is a powerful and corrosive chemical that is used in a variety of industries, such as the production of inorganic chlorides, the manufacture of chlorinated compounds, and the production of dyes and pigments. It is also used in pickling and acidifying processes, as well as in the chlorination of drinking water.
Common types of failures when rubber is exposed to hydrogen chloride gas include discoloration and cracking due to the strong oxidizing properties of the gas, as well as embrittlement due to the corrosive nature of the acid. Additionally, rubber seals exposed to hydrogen chloride gas may become brittle and prone to cracking or tearing over time, as the acid slowly breaks down the rubber material.
