5mm Microjet Air Valves are used in conjunction with 4mm or 5mm flexible air tubing in order to regulate the volume of air flowing passing through the tube. They are perfect for aquaponic systems, hydroponic systems, and koi ponds where the amount of air passing through needs to be adjusted. With the Microjet Air Valves the air passing through can be turned off at any time when not required.
The 5mm Microjet Air Valves have 5mm barbs at each end and are perfect for inserting into 4mm or 5mm air tubing.
Please note that the air valves do not necessarily shut off completely.
