This is an assembled flow restrictor unit that can fit into an 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 0.5GPM per min, and should be used when using lengths of BluSoak between 1500 to 2500 feet.
