HYDROGEN GAS, HOT Chemical compatibility with O-rings, rubbers, & plastics

Hydrogen gas (H₂) is a colorless, odorless, and highly flammable gas used in various industrial applications, including ammonia synthesis, petroleum refining, and as a reducing agent in metallurgy. Hot hydrogen gas is employed in high-temperature processes to enhance reactivity and efficiency. Despite its industrial importance, hydrogen gas poses significant safety hazards due to its flammability and potential for explosive mixtures with air. Proper handling, storage, and stringent safety measures, including leak detection and adequate ventilation, are essential to ensure safe usage and minimize risks associated with hydrogen gas, especially at elevated temperatures.
