Flow recommendations
The RFG Nozzle will handle far more flow than the "Optimal" GPH recommendations, so we encourage you to experiment and test the limits of the RFG Nozzles.
 
 
1/2in Random Flow Generator® Nozzle
The Only Random Flow Device With No Moving Parts.
The RFG Nozzle represents the next evolution in hydrodynamic design.
The unique patented internal design of the Random Flow Generator, leverages fluid dynamics to randomly alter the direction of the flow as it exits the nozzle.

The RFG Flex Series will build on this trust earned over the years by delivering a new level of durability, flexibility and an enhanced functionality.
This internal helix design, pulls the central jet in on of 5 possible direction, but in only one direction at a time. The result is a broad wave-maker like motion but with no moving parts to ware out, no noise and no addition heat generated.
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.
Flexibility in Fitting
RFG Flex Series Nozzle will fit genuine Loc-Line® brand modular hose but also adapt to fit other similar sized modular hose fittings.
The RFG Flex Series is directly compatible with a wider range of aquariums and modular hose designs.
 
 
Durability
Made with a strong, extremely durable and flexible material, the RFG Flex Series won’t crack, it can’t break and has superior durability.
It’s also extremely easy to clean, since most algae and bio films simply slide right off with minimal effort
