Why are oxygen valve threads designed to be right handed?

The design of oxygen valve threads as right-handed is primarily intended to avoid confusion with acetylene connections, which are typically left-handed. This differentiation is crucial in preventing the accidental attachment of the wrong gas, which can lead to dangerous situations. Since acetylene and oxygen are used together in welding and cutting processes, ensuring clear and distinct threading helps maintain safety and compatibility. This standardization in design is a critical aspect of gas handling protocols, as it aids users in easily identifying and connecting the appropriate tanks for their applications.
