Hydrochloric acid, also known as muriatic acid, spirits of salt, and chlorhydric acid, is used in various industries such as metal processing, food processing, production of inorganic chemicals, and the manufacture of dyes.
When rubber is exposed to hydrochloric acid, at a concentration of 3 molar and at temperatures of 158°F, the rubber material can experience rapid swelling, softening, cracking, and degradation. The reaction is accelerated at higher temperatures and higher concentrations, leading to increased vulnerability to failure of the rubber seal due to cracking, discoloration, and surface etching.
Viton ® o-rings from Marco Rubber offer excellent compatibility with a range of chemicals, oils and resist high temperatures up to 400F. Viton ® is also known as FKM made of fluoroelastomer one of the most versatile and widely used sealing materials.
