Airline Tubing – 3m

Standard clear airline tubing is one of the most frequently needed consumables in any fishroom. This 3m length is sufficient for most single-tank setups, connecting an air pump to an air stone, sponge filter, or gang valve with room to route the hose neatly along the tank frame.

The 4mm internal diameter is the universal standard that fits all common airline accessories including air stones, check valves, gang valves, CO2 diffusers, and acclimation drip kits. The clear PVC material allows the keeper to inspect for blockages and confirms that bubbles are flowing through the line.

Airline tubing should be replaced when it becomes discoloured, brittle, or develops permanent kinks that restrict airflow. Keeping a spare roll on hand avoids interruptions to aeration or filtration.
