2 Pieces of 4mm Air line flat none-return valves - check valves - Blue
The none-return valves are to prevent water running back into the air pump which quite often happens when the air pump stops.
They are suitable for air and liquids and give easy control by just inserting into the air line making sure the flow direction is checked
