LINLAN 4-Pack Aquarium 304 Stainless Steel U Pipe Fitting, Anti-Kink Design, Compatible with 4mm (0.16 Inch) ID Tube, Air Pump and CO2 Diffuser Accessories, for Rimless Aquariums

• 【MIRROR POLISHED 304 STAINLESS STEEL】: Crafted from 304 Stainless Steel, resistant to corrosion and abrasion, remains anti-ageing even with long-term immersion, easy to clean and scratch-free.
• 【COMPATIBLE WITH SHORT CO2 DIFFUSERS】: Many short stainless steel/metal CO2 diffusers cannot be hung directly on the aquarium wall and often look messy. Using the U Fitting allows for a neat and aesthetic layout.
• 【PREVENTS KINKING AND ENSURES STABLE AIRFLOW】: Airline tubing is often flexible and prone to sharp bends, which compress the inner diameter, reduce air output, and create a messy look. The U Pipe allows for a smooth bend, preventing kinks, ensuring optimal airflow while maintaining a tidy appearance. Suitable for sponge filters and air stones.
• 【FLEXIBLE HANGING, EASY WATER CHANGES】: The adjustable hanger adapts easily to different aquarium wall heights and angles, simplifying water changes. One-tap positioning for draining and refilling, improving maintenance efficiency.
• 【UNIVERSAL FOR RIMLESS AQUARIUMS】: Suitable for most rimless aquariums using standard CO2 systems or air pumps, with glass thickness up to 16mm (0.63 inches). Compatible with check valves to prevent backflow.
