Our high quality black air line is ideal for use with all aquarium and pond air pumps which accept standard 4mm internal (6mm external) diameter air line.

This air line is black in colour – allowing it to better blend into aquarium backgrounds and can be run into the tank down the black seal and under the gravel to give an uninterrupted view of the aquarium.

This air line is available in a variety of lengths (5m, 10m, 15m, 20m and 25m). Please select the size required from the drop-down menu when ordering.
