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

Hydrochloric acid (cold) 37% is a concentrated aqueous solution of HCl, widely used in industrial and laboratory settings. This strong, highly corrosive acid is essential for metal refining, chemical synthesis, and pH control in various processes. It is also used in the food industry for processing and preserving products. At 37% concentration, hydrochloric acid poses significant health risks, including severe burns and irritation to the skin, eyes, and respiratory tract. Proper handling, storage, and the use of personal protective equipment are crucial to ensure safety when working with this concentrated acid. Special care is needed when handling cold solutions to prevent thermal shock and splashing.
