Which type of joints are prohibited in medical gas systems?

In medical gas systems, compression type joints are prohibited primarily because they can lead to potential failures or leaks. Medical gas systems are critical for providing safe and reliable medical gases, such as oxygen, nitrous oxide, and medical air, and any leaks could have serious implications for patient safety and treatment efficacy. Compression joints, while commonly used in various plumbing applications, can be less reliable in high-pressure scenarios and under varying temperatures, increasing the risk of gas leaks over time.

Other types of joints, such as brazed and welded joints, are generally favored in medical gas systems due to their strength and leak-resistant properties. Brazed joints are particularly suitable for high-pressure systems and resist the issues that can arise in compression fittings. Soldered joints, while having some limitations in pressure applications, can also be acceptable under certain conditions, provided they adhere to the established safety standards and practices.

The stringent requirements for medical gas systems emphasize the need for dependable and durable connection methods, which is why compression type joints are not permitted.
