What type of connections do oxygen hoses usually have?

Oxygen hoses typically have right-handed threaded connections. This design is intentional to prevent any mix-up between oxygen and acetylene hoses, ensuring safety in oxyfuel cutting operations. The right-handed threads are established standards that make it easy to identify and connect oxygen hoses correctly. This helps in avoiding potentially dangerous situations that could arise from using the wrong gas.

The right-handed threading means that these connections tighten when turned clockwise—an intuitive and widely understood mechanism. This standardization is critical in environments where multiple gas hoses may be used, as it reinforces proper use and handling practices that are essential in oxyfuel cutting to maintain safety and efficiency.

Other types of fittings and connections may exist in various applications, but for oxygen hoses in the context of oxyfuel cutting, the use of right-handed threads is a crucial feature that promotes safe handling and operational integrity.
