The Sink Mate Hospitality is designed to economically, and accurately dilute detergent and sanitizer to fill kitchen sinks. The dispenser is made with minimal number of parts and a toolless cover design, making servicing and installation simple. The compact case fits nicely into small kitchen areas and the impact resistant cover design allows the unit to with stand the wear and tear in the kitchen environment. Both the 4 GPM Flex-Gap and 4 GPM Aire-Gap dilutes chemical at the same ratio allowing you to use the same metering tip or pre-metered cap for both Flex-Gap and Aire-Gap.
