Premium Compact Directional Duckbill Nozzle (16-40mm I.D.) | 360° Adjustable Aquarium Water Outlet | Nano & AIO Rear Filter

Premium Compact Directional Duckbill Nozzle

Maximize your water circulation in tight spaces with the Compact Directional Return Nozzle from Atradesen.com. Specifically engineered for All-In-One (AIO) rear filters, side compartments, and nano tanks, this short-profile flow director eliminates dead spots and detritus buildup without intruding into your aquascape's swimming space.

🌟 Space-Saving & Low Flow-Loss Design

• Ultra-Compact Profile: The short body design is perfect for cramped filter chambers where standard long nozzles simply won't fit.
• High-Flow Internal Cavity: Features an optimized, raised internal chamber that significantly reduces water friction, ensuring you don't lose valuable pump flow rate while reducing splashing noise.
• 360° & ±30° Adjustability: The built-in ball joint allows you to rotate the duckbill a full 360 degrees and tilt it up to 30 degrees in any direction to perfectly aim your flow.

⚠️ Sizing & Dual Connection Guide (Crucial!)

This clever nozzle features a "Dual Connection" design. Please read the Atradesen.com fitment rules carefully before ordering:

• Method 1 (Use the Inner Diameter - I.D.): The nozzle's I.D. is designed to sleeve OVER a rigid PVC pipe. (e.g., A 20mm I.D. nozzle fits perfectly OVER a 20mm O.D. PVC pipe).
• Method 2 (Use the Outer Diameter - O.D.): The nozzle's O.D. is designed to plug INTO a PVC fitting (like an elbow) or into a soft silicone hose. (e.g., A 25mm O.D. nozzle plugs perfectly INTO a 25mm I.D. elbow fitting or hose).
• Installation: Can be snugly push-fitted for easy adjustment, or permanently glued using PVC cement for high-pressure systems.
