Glass U Tube – Airline Guide for CO₂ & Aquarium Tubing

Create a cleaner, more professional aquarium setup. The 20mm Glass U Tube neatly guides airline tubing over the aquarium rim while preventing kinks, creases, and visual clutter.

Key Benefits:

• Prevents airline tubing from bending or creasing
• Ideal for CO₂ and air supply systems
• Clear glass design minimizes visibility
• Helps maintain neat, organized tubing layout
• Suitable for planted and marine aquariums

Bent or pinched airline tubing can restrict airflow or CO₂ delivery, reducing system efficiency. A properly positioned U Tube helps maintain smooth, uninterrupted flow while improving the appearance of your setup.

The U-shaped glass guide allows tubing to pass smoothly over the aquarium rim without sharp bends or pressure points.

Compatible with:

• 6mm (1/4") standard airline tubing
• Silicone airline tubing (recommended)

If you want a cleaner, more organized aquarium setup with improved tubing management, the 20mm Glass U Tube is a simple but highly effective addition to your system.
