Aquarium Airline Tubing, Valves, Connectors & Air Stones

Connect and organise your aquarium aeration setup with airline tubing, check valves, airflow controls and connectors from The Tech Den Australia. This collection also includes air stones, diffusers, air bars and LED bubble curtains, with products from Aqua One, Bioscape, Serenity, Dymax and other brands.

Airline tubing and aeration accessories

Silicone and PVC airline in selected lengths, including by-the-metre tubing, 5m packs and a 100m roll.
Check valves, adjustable control valves and gang valves for different airline arrangements.
T connectors, elbows and suction cups for routing and securing tubing.
Ball, disc and bar air stones, flexible bubble curtains and illuminated bubble displays.

Match the parts to your setup

Check tubing dimensions, outlet fittings and package quantities on each listing before ordering. Choose air stones and curtains to suit the available space, and check the air pump requirements for your aquarium depth and number of outlets. Airflow controls and connectors have different functions: a splitter is not necessarily an adjustable valve or a one-way check valve. Follow the pump and accessory instructions for installation and check-valve direction.

CO2 splitters and inline diffusers, ATO hose, pond fittings and model-specific accessories also appear in this collection. These are not interchangeable with standard aquarium airline components; confirm the intended application and equipment compatibility.

Before ordering

Check whether an air pump, tubing and any required electrical supply are included or sold separately. Selected long air bars are in-store pickup only, and some larger bubble curtains have additional delivery charges. Refer to the individual listing for length, pack contents and purchasing restrictions.
