Premium PVC Duckbill Return Nozzle (O.D 8-29mm) | 90° Elbow Water Outlet for Aquarium Pumps & Soft Hoses

Premium PVC 90° Duckbill Return Nozzle

Upgrade your aquarium's water circulation with our versatile Duckbill Nozzles from Atradesen.com. Designed specifically for flexible hoses and submersible pump outlets, this 90-degree directional nozzle creates a wide, flat water stream that massively improves surface agitation and overall flow dynamics.

🌟 Versatile & Detachable Design

• Broad Flow Dynamics: The flattened duckbill shape naturally accelerates and spreads out the water flow, creating excellent surface movement for oxygenation or sweeping heavy detritus across the bare tank bottom.
• Detachable 90° Elbow: Features a smart modular design that can be easily taken apart for routine cleaning. The 90-degree bend directs flow perfectly without kinking your soft silicone or vinyl tubing.
• Universal Pump Compatibility: Ideal as a directional return for 3-in-1 submersible pumps, external canister filters, and custom DIY plumbing setups.

⚠️ Sizing & Soft Hose Fitment Guide (Crucial!)

Please measure your hoses carefully. The dimensions listed on Atradesen.com refer to the nozzle's round connection port:

• Inner Diameter (I.D.): Refers to the inside hole of the nozzle's connection port.
• Outer Diameter (O.D.): Refers to the outside width of the nozzle's connection port. 🚨 IF CONNECTING TO A SOFT HOSE: The nozzle's O.D. must be equal to or slightly larger than your hose's Inner Diameter for a snug, watertight friction fit!
• 💡 Pro Tip: The 12mm O.D. model features a specialized barbed end with a small air-intake port (Venturi effect) for active aeration!
