0 SWIVEL DISCONNECT™ FITTINGS OXYGEN THREAD – DIAMETER INDEX SAFETY SYSTEM (DISS) FITTINGS Eldon James Swivel Disconnect™ Oxygen Thread DISS fittings are a reliable, ball-seat construction disconnect system with no springs, gaskets or O-rings. 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 a 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 9/16″-18 thread connections as its safety standards.
