Diameter-Index Safety System (DISS) connectors are threaded and have a unique diameter for each type of gas to prevent accidental hookup of the wrong gas. These specific diameters act in key-like fashion, so that fittings within the gas service “family” will connect only with their own “family members.” In place of diameter indexing, Oxygen (DISS 1240) has been assigned the long established 916″-18 thread connections as its safety standards.
