Standards and Specifications for Gas Valve Connections Worldwide

Global Gas Connections and Standards

Gas cylinders and their connections play a crucial role in various industries, such as medicine, welding, diving, and technical applications. To ensure safety, efficiency, and compatibility between different systems, global standards for thread types and gas cylinder connections have been developed. These standards ensure that valves and accessories can be correctly connected to prevent leaks, malfunctions, and hazards.

Some of the most well-known standards include ISO standards, which establish international guidelines for thread types and valve connections. In addition, there are regional and country-specific standards, such as DIN (Germany), CGA (USA), BS (United Kingdom), and JIS (Japan). These standards differ not only in thread types but also in pressure ranges, materials, and the gases used.

Some of the most common thread types are:

• DIN Threads: Widely used in Europe, especially in Germany and neighboring countries.
• CGA Connections: Standard in the USA, particularly for industrial and medical applications.
• BS 341: Used in the United Kingdom, mainly for technical gases.
• ISO 5145: A global standard that governs various thread types for high-pressure gas cylinders.

The differences between these standards are also reflected in the use of specific gases. For example, oxygen, helium, nitrogen, or acetylene require specialized connections to ensure safe handling.
