    Premium 360° Adjustable Duckbill Return Nozzle

    Perfect your aquarium's water flow dynamics with our Universal Adjustable Duckbill Nozzles from Atradesen.com. Designed as the industry-standard return fitting, this highly versatile nozzle allows you to precisely direct water currents, eliminate dead spots, and significantly reduce splashing noises in any freshwater or marine setup.

    🌟 Advanced Flow Control & Smart Features

    • 360° Rotation & ±30° Tilt: The built-in ball joint allows for complete freedom in directing your water flow exactly where your corals or aquascape need it.
    • Single vs. Double Head Options: Choose the Single head for direct flow, or upgrade to the Double head (T-shape) to split your return pump's output into two independently adjustable streams!
    • 💡 The "Air Hole" Magic (Transparent Model Only): The special model with an air port serves two incredible functions! 1. Anti-Siphon Break: If placed slightly above the water line, it sucks in air when the pump stops, instantly preventing catastrophic back-siphoning. 2. Venturi Aeration: When fully submerged, the rapid water flow creates a vacuum that sucks in air through the hole, blasting highly oxygenated micro-bubbles into your tank!

    ⚠️ Dual-Connection Sizing Guide (Crucial!)

    This clever nozzle features a "Dual Connection" design, making it the most compatible fitting on the market. Please read the Atradesen.com fitment rules carefully:

    • Method 1 (Use the Inner Diameter - I.D. 20mm): The nozzle's base is designed to sleeve OVER a rigid PVC pipe with a 20mm Outer Diameter (O.D.).
    • Method 2 (Use the Outer Diameter - O.D. 25mm): The nozzle's base is designed to plug INTO a PVC fitting (like a 25mm elbow or tee) that has a 25mm Inner Diameter (I.D.).
    • Material Note: All colored nozzles (Black, White, Blue) are made of durable PVC. All Transparent nozzles are made of high-clarity Acrylic.
