HYDROCHLORIC ACID (HOT) 37% Chemical compatibility with O-rings, rubbers, & plastics

Hydrochloric acid (hot) 37% is a concentrated solution of HCl in water, used in various industrial and laboratory applications. This strong, highly corrosive acid is essential for metal refining, chemical synthesis, and pH control. When heated, hydrochloric acid becomes even more reactive, making it particularly effective for cleaning and etching metals. However, hot hydrochloric acid poses significant health and safety risks, including severe burns and respiratory irritation. Proper handling, storage, and safety measures, including the use of personal protective equipment and adequate ventilation, are crucial to ensure safe usage and prevent accidents.
