DISS Style Medical Gas Fittings – The Diameter Index Safety System (DISS) is a standardized system used in medical gas delivery systems to ensure that the correct gas is delivered to the correct device or equipment. The DISS system is designed to prevent accidental connections between incompatible gases, which can lead to serious and potentially life-threatening situations.

The DISS system consists of a series of color-coded fittings and outlet connections, each corresponding to a specific gas. For example, oxygen outlets are designated with a white ring, while nitrous oxide outlets are designated with a blue ring.

The DISS system also includes a standard thread size for each gas outlet, which ensures that only the appropriate equipment can be connected to each gas source. This helps prevent the accidental connection of equipment that is not compatible with a specific gas, which could cause leaks or other dangerous situations.

The DISS system is widely used in medical gas delivery systems in hospitals, clinics, and other healthcare facilities. The system is recognized and recommended by various organizations, including the National Fire Protection Association (NFPA), the American Society of Anesthesiologists (ASA), and the Food and Drug Administration (FDA).

In summary, the Diameter Index Safety System (DISS) is a standardized system used in medical gas delivery systems to ensure that the correct gas is delivered to the correct device or equipment. The DISS system helps prevent the accidental connection of incompatible equipment, which can lead to serious and potentially life-threatening situations.
