This is an assembled flow restrictor unit that can fit into a a 8mm supply line.

Flow controllers work similar to a pressure reducer, but instead limit the certain flow rate that can be entered into a system.

We use Flow controllers in our BluSoak systems in order to limit the total amount of water that can enter the system, this acts as a safety mechanism to make sure you do not flood your system too rapidly in case of any errors.

This particular product limits the flow of our mega drip tape to 0.15GPM per min, and should be used when using lengths of BluSoak between 200 to 750 feet.
