Abstract
A two-part key coded device that can be added to existing container and dispense stations. The key coded device includes a female key ring that is retrofitted to an existing bung and a compatible male key ring that is retrofitted to an existing or new dispense head. The key code system can enable only a specific or compatible type of chemical to be connected to the dispense head, and provides a measure of safety against inadvertently connecting the wrong type of chemical.
