Specialty valve fittings for your custom water loop are ball valves, designed to stop the flow of coolant when needed. By turning the handle on the valve, water flow is stopped inside the valve. Used primarily for drain ports, valve fittings can be used for anything requiring that coolant be stopped. Placing a valve fitting on either side of a filter fitting for instance will allow the filter to be removed and cleaned without draining the system. TITAN RIG stocks valve fittings in both double-female and male-female configurations, some with rotary connection as well. Several colors and styles are available to choose from.
