The Patented

Random Flow Generator® Nozzle

The Only Random Flow Device With No Moving Parts.

The Random Flow Generator® Nozzle has a unique patented internal design that uses fluid dynamics to randomly vary the intensity and direction of the flow as it exits the nozzle.

The Random Flow Generator® or RFG Nozzle can help to create a more natural, randomized flow pattern within an aquarium, pond, or other bodies of water.

Sizing

Each Random Flow Generator is designed to snap on to genuin Loc-line fittings or slip-fit to standard PVC pipe. For exmaple, the 1/2in Random FLow Generator will connect directly to genuine 1/2in Loc-Line modular hose.
