Rain Bird BVAL50-1S Drip Irrigation 12 Barbed Valve, Male x Male

This Rain Bird BT504PKS is a drip irrigation universal barbed tee fitting that is compatible with 1/2" drip tubing whose inner diameter is between 0.53" and 0.60". It comes in a 4-pack and can be used to control water flow for flushing heater core or to lessen the flow of water for an aquaponics set up. The fitting is not a true ball valve, but it is a simple valve that works like the valves underneath your bathroom sink. One can keep the water from blasting into the sink by adjusting the flow with the valves. Customers appreciate the simplicity of installation and of not having to keep track of parts for two different sizes. However, some customers have found that different suppliers' tubing and adapters do not fit the same, so they need to use additional clamps or silicone adhesive. Overall, reviewers find that this valve is a useful addition to their drip irrigation system. **
