loc line duckbill nozzle for aquarium

Increase your aquarium's circulation efficiency with this articulated return kit. Designed to offer total control over flow direction, this system eliminates dead spots in circulation and ensures nutrients and oxygen reach all corners of the tank, essential for planted or coral aquariums.

Key Features:

• 360° Articulation: The modular system allows for precise manual adjustment to direct the water jet without leaks or pressure loss.
• Hybrid Compatibility: Includes a connection for a 1/2 inch thread and a specific adapter for 3/4 inch PVC pipes, facilitating installation in various filtration systems and sumps.
• Optimized Flow Design: The internal shape reduces water restriction, maintaining your return pump's performance.

Filament Recommendation: PETG

For 3D printing these parts, using PETG is highly recommended. Unlike PLA, which can slowly biodegrade underwater, PETG is inert and safe for the aquatic ecosystem, in both fresh and saltwater.

• Why use PETG? It has high thermal and chemical resistance, does not deform with water temperature, and does not release toxic substances. Additionally, its natural flexibility aids in the pressure fitting of the Loc-Line segments, preventing the part from breaking during adjustment.
