Premium PVC Inline Oxygenation Tee Fitting (20mm ID) - 4-6mm Airline Barb Adapter

Premium PVC Inline Oxygenation Tee Fitting

Dramatically increase dissolved oxygen levels in your aquarium or hydroponic setup with our Premium PVC Inline Oxygenation Tee Fitting. Instead of cluttering your display tank with unsightly air stones, this specialized adapter allows you to inject air directly into your main water flow. Designed with a standard 20mm inner diameter to seamlessly fit standard rigid pipes, it features an integrated stepped barb that securely connects to your air pump's silicone tubing. Build a cleaner, more efficient aquatic life-support system with professional hardware from Atradesen.com.

Why Choose Our Oxygenation Tee?

• Maximum Aeration Efficiency: Injecting air directly into the flowing water inside your plumbing creates a powerful mixing action (similar to a venturi injector). This maximizes the contact time between micro-bubbles and water, resulting in significantly higher dissolved oxygen rates.
• Universal Airline Barb: The side inlet features a stepped barb (4-6mm Outer Diameter) that tightly grips standard 4mm/6mm aquarium airline tubing. This prevents high-pressure blow-offs and ensures a secure, leak-free air supply connection.
• Premium Aquarium-Safe PVC: Molded from high-quality, non-toxic blue PVC (not UPVC), this fitting is perfectly safe for all sensitive freshwater, marine reef, and aquaculture environments. It resists cracking, pressure fatigue, and degradation over time.

⚠️ Installation Guide: The main body features an Inner Diameter (ID) of 20mm (to slip over 20mm rigid pipes) and an Outer Diameter (OD) of 25mm (to slip inside 25mm fittings). For a permanent and watertight system, use aquarium-safe PVC solvent cement on the main slip connections. Push your 4-6mm silicone or PVC air hose firmly over the barbed inlet until secure.
