Seachem Glass U-Tube – 10 mm / 20 mm
Seachem Glass U-Tube offers an elegant and practical solution for routing COâ‚‚ or airline tubing over the edge of your aquarium. Manufactured from clear glass, its smooth U-shaped design prevents flexible tubing from bending, kinking, or restricting airflow while maintaining a clean, minimalist appearance.
Ideal for planted aquariums, COâ‚‚ injection systems, and air pumps, the Seachem Glass U-Tube is available in 10 mm and 20 mm sizes to accommodate different aquarium rim thicknesses.
Clean, Kink-Free Tubing Installation Guide your COâ‚‚ or airline tubing neatly over the aquarium rim without sharp bends or unsightly loops. The transparent glass construction blends beautifully into modern aquascapes.
Which Size Should I Choose?
The 10 mm and 20 mm measurements refer to the clearance between the two sides of the glass U-Tube, NOT the tubing diameter. Both sizes are compatible with standard 6 mm (1/4") airline tubing.
| Size |
Recommended Aquarium |
Rim Clearance |
| 10 mm |
Most rimless aquariums |
For aquarium edges thinner than 10 mm |
| 20 mm |
Most rimmed aquariums or thicker glass tanks |
For aquarium edges requiring up to approximately 20 mm clearance |
Not Sure Which Size to Order? Measure the total thickness of your aquarium's top edge, including any plastic trim. Choose the size that provides enough clearance to fit comfortably over the rim. For example, a rimless aquarium with 6 mm glass would typically use the 10 mm version, while a thicker plastic-rimmed aquarium may require the 20 mm version.

Installation Instructions
- Rinse the glass U-Tube thoroughly with warm water.
- Cut your compatible airline tubing to the desired lengths.
- Moisten the inside of the tubing with water and carefully slide it onto each end of the glass U-Tube.
- Install an appropriate check valve separately if required by your setup.
- Carefully position the U-Tube over the aquarium rim without applying pressure to the glass.
Glassware Care Tip Glass aquarium accessories are fragile. Never force tubing onto or off the glass connections. When removing tubing, carefully cut it lengthwise at the attachment point rather than pulling, which could break the glass.
Keep your aquarium tubing organized and your aquascape looking its best with the Seachem Glass U-Tube, available in 10 mm and 20 mm at Aquascaperoom Canada.
