Ohio quick-connect (OQC) system

The Ohio quick-connect system, like the DISS, is a gas station outlet system used in the hospital setting for the supply of medical gases. Ohio quick-connectors have a unique arrangement of a two-pin and groove connection for each type of gas to prevent erroneous connection. Disconnection is by twisting a ring around the male connector which operates a spring-release mechanism. The system also contains a valve at the outlet/ wall supply side which shuts off gas supply upon disconnection.

Like the DISS connectors, the Ohio quick-connect system is color-coded for the medical gas supplied.
