Extremely Durable and Flexible Material
Manufactured with a reef-safe TPU (Thermoplastic Polyurethane)

Wide compatibility
Works with genuine 3/4in Loc-Line modular hose and most other modular hoses of similar size

Unique Patented Internal Design
Same trusted design as the original Random Flow Generator® Nozzle

Includes a single Flex Series 3/4in Random Flow Generator® Nozzle
Flexibility

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.

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.

Model Minimum GPH Suggested Optimal Flow
Single 3/4in RFG 180-200 GPH 420-500 GPH
(680-757 LPH) (1,590 – 1,890 LPH)

Two 3/4in RFGs 400-500 GPH 700-900 GPH
(1,500-1,890 LPH) (2,600-3,028 LPH)

Extremely Durable and Flexible Material

Wide compatibility
Works with genuine 1/2in Loc-Line modular hose and most other modular hoses of similar size

Unique Patented Internal Design

Includes a single Flex Series 1/2in Random Flow Generator® Nozzle
Flexibility

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.

Flow recommendations
For the strong, punchy randomization flow effect, supply each Random Flow Generator® Nozzle with the Suggested Optimal Flow Rating or more. For broad diffused and randomized flow, your target should be closer to the suggested minimum flow.

Model Minimum GPH Suggested Optimal Flow
Single 1/2in RFG 120-150 GPH 300-450 GPH
(545-680 LPH) (1,363 – 1,890 LPH)

Two 1/2in RFGs 250-400 GPH 640-6700+ GPH
(1,136-1,818 LPH) (2,900-3,045 LPH)
