Several sizes are available: 12 mm valves fit tubing with a 12 mm (0.5 inch) inner diameter and a 16 mm (0.6 inch) outer diameter; 16 mm valves fit tubing with a 16 mm (0.9 inch) inner diameter and a 22 mm (0.9 inch) outer diameter. Quick installation and easy removal: simply close both valves and place the connector in the open position to easily separate the aquarium and filter for convenient cleaning.
