Flexible Airline Tubing 3m

The Flexible Airline Tubing 3m is a standard length of clear PVC aquarium-grade airline tubing suitable for connecting air pumps, gang valves, check valves, airstones, sponge filters, and any other device in the aquarium aeration system. The 3-metre length provides enough tubing for most standard single-tank setups from pump to device without excess waste.

The clear PVC construction allows visual inspection of airflow and easy identification of any water that may have entered the line. The standard 4mm internal diameter is compatible with all common aquarium airline fittings, barbs, and connectors. The flexible yet firm material holds its shape well at room temperature, resisting kinking under normal routing conditions.

This tubing is suitable for use with standard air pumps operating at typical aquarium pressure levels. It is not recommended for very high-pressure commercial applications where silicone or reinforced tubing is preferred. The 3m length suits single tanks, nano setups, and short routing situations.
