LINLAN 4-Piece Aquarium Glass U-Tube Connector, Anti-Kink Design,for 5/16 inch (4mm) ID Air Hose,Fits Air Pumps & CO2 Diffusers，Accessory for Rimless Aquariums

About this item

• 【CRYSTAL-CLEAR GLASS CONSTRUCTION】Made from high-quality transparent glass, this U-shaped connector maintains an unobstructed view without disrupting the visual flow of your aquascape—perfect for aquariums where aesthetics matter.
• 【SHORT CO₂ DIFFUSER COMPATIBILITY】Many short glass or acrylic CO₂ diffusers cannot be mounted directly on the aquarium wall and often look messy. This U-shaped connector neatly organizes the air tubing, keeping it flat and tidy for a clean, aesthetic setup.
• 【PREVENTS TUBING KINKS, ENSURES CONSISTENT AIRFLOW】Oxygen tubing is often flexible and prone to sharp bends, which compress the inner diameter, reduce air output, and create a messy appearance. The U-shaped tubing guides the tubing in a smooth curve, preventing kinks and ensuring optimal airflow while maintaining a neat appearance. Suitable for sponge filters and air chambers.
• 【SCRATCH-RESISTANT & EASY TO CLEAN​】Unlike acrylic tubes,which are prone to scratching and cloudiness after cleaning—especially when dealing with algae buildup—this glass U-connector is scratch-resistant,wipes clean easily, and maintains its clarity even after repeated washing.
• 【UNIVERSAL FIT FOR RIMLESS AQUARIUMS】​Compatible with most rimless aquariums using standard CO₂ systems or air pumps for tanks with glass thickness under 15mm (0.59in). Compatible with check valves to prevent backflow.
