What is bubbler tubing?
Bubbler tubing is porous tubing designed to act as an air diffuser. When connected to an air pump and submerged, air escapes through the tubing wall to create bubbles along its length.

4mm Bubbler Tubing – 50m Porous Air Diffuser

£50.00
Unit price perEstimated delivery between September 15 and September 17.
50m roll of porous 4mm bubbler tubing for creating custom-length air diffusers and an even wall of bubbles in hydroponic reservoirs.
This 4mm Bubbler Tubing gives growers a flexible alternative to conventional air stones. Instead of carrying air to a separate diffuser, the porous tubing releases air through its surface, producing bubbles along the length of the tube.
Supplied as a 50m roll, it can be cut and arranged to suit different reservoir shapes and aeration layouts. This makes it particularly useful for custom hydroponic systems, larger nutrient tanks and applications where you want to spread aeration across a wider area rather than concentrate it around a single air stone.
The tubing has a 4mm internal diameter and approximately 9mm external diameter. Connect it to a suitable air supply, close the far end and position the porous section within the reservoir to create your own air diffuser.
Why choose 4mm Bubbler Tubing?
- Creates a wall of bubbles – porous tubing disperses air along its length rather than from one single outlet.
- Custom aeration layouts – cut the tubing to suit individual reservoirs and growing systems.
- 50m roll – provides plenty of tubing for larger installations or multiple aeration sections.
- 4mm internal diameter – suitable for integration with compatible aeration fittings and air supplies.
- Flexible positioning – arrange the tubing to spread bubbles across the area where aeration is needed.
- Ideal for hydroponics – useful in nutrient reservoirs, DWC systems and custom hydroponic installations.
What is bubbler tubing used for?
Bubbler tubing is a porous air diffuser supplied in flexible tube form. When connected to an air pump, air passes through the walls of the submerged tubing and creates a fine, even spread of bubbles.
Because the tubing itself acts as the diffuser, growers can create aeration layouts that follow the shape of a reservoir or cover a wider area than a small individual air stone. It is particularly useful for DIY hydroponic systems and custom reservoir setups.
Bubbler tubing or an air stone?
A conventional air stone concentrates aeration around a fixed diffuser. Bubbler tubing allows the diffusing area to be extended along a chosen length, giving you more freedom over where bubbles are produced within the reservoir.
This makes bubbler tubing a useful option for long tanks, larger reservoirs and unusual layouts where several fixed air stones would otherwise be needed to spread aeration across the available space.
How to use 4mm Bubbler Tubing
Cut the bubbler tubing to the required length for your reservoir or aeration layout. Connect one end to a compatible airline supply from a suitably sized air pump, using the appropriate connector where required.
Seal the opposite end with a compatible stop end so that the incoming air is forced through the porous wall of the tubing. Position the bubbler tubing below the surface of the water or nutrient solution, then switch on the air pump and check that bubbles are being produced along the required section.
Longer lengths of bubbler tubing place greater demand on the air supply, so the connected pump should be sized for the amount of tubing being operated and the level of aeration required.

4mm Bubbler Tubing FAQs
Does bubbler tubing replace an air stone?
Yes, it can. The porous tubing itself acts as the diffuser, so a separate air stone is not required at the end of the bubbler section.
What size is this bubbler tubing?
The tubing has a 4mm internal diameter and approximately 9mm external diameter. This product is supplied as a 50m roll.
Can I cut bubbler tubing to length?
Yes. One of the main advantages of bubbler tubing is that it can be cut to create an aeration section suited to the reservoir or hydroponic system being built.
Do I need to seal the end of bubbler tubing?
Yes. The far end should be closed with a compatible stop end so that the supplied air is forced through the porous tubing rather than escaping freely from the open end.
Can I use bubbler tubing in a hydroponic reservoir?
Yes. It is particularly useful for hydroponic reservoirs because the tubing can be positioned to distribute bubbles across a wider area of nutrient solution.
Is bubbler tubing suitable for DWC?
Yes. Bubbler tubing can be used as a diffuser in DWC systems where continuous nutrient solution aeration is required.
What air pump do I need for bubbler tubing?
The required pump capacity depends on the length of bubbler tubing being operated and the aeration required. Longer diffuser runs need a greater air supply than short sections, so the pump should be sized for the complete setup.
Can I make a custom-shaped air diffuser with bubbler tubing?
Yes. Its flexible format makes bubbler tubing useful for creating custom aeration layouts within reservoirs where a conventional fixed air stone may not provide the desired coverage.
