Glass U-tube with 17–18 mm bend spacing and 5 mm diameter, ideal for guiding CO2 or air tubing over the edge of an aquarium. It helps prevent hose kinking and keeps the setup neat and tidy. It also reduces tension from CO2 tubing on diffuser suction cups, helping to prevent them from repeatedly coming loose from the glass and keeping the diffuser properly positioned. The U-tube is also ideal as an end piece for tubing from automatic dosing systems.
