£1.10

6 way plastic airline manifold for splitting one 8mm air supply into six separate 4mm airline feeds.

This 6 Way Plastic Airline Manifold provides a simple way to distribute air from one larger air pump or compressor across multiple air stones, diffusers or aeration points.

A single 8mm inlet feeds six 4mm outlets, allowing you to run several standard airline connections from one central point. It is a straightforward way to create a cleaner, more organised aeration setup without needing a separate pump outlet for every air stone.

Ideal for hydroponic reservoirs, DWC systems and other growing setups where several aeration points need to operate from the same air supply.

Why use a 6 Way Airline Manifold?

  • Six separate air outlets – split one air supply between up to six individual airline runs.
  • 8mm inlet – connects the manifold to a suitable larger airline from an air pump or compressor.
  • Six 4mm outlets – designed for connecting smaller airline runs to air stones and other aeration equipment.
  • Ideal for multi-point aeration – useful for running several air stones from one larger air pump.
  • Keeps airline organised – brings multiple branches together at one central distribution point.
  • Useful for hydroponic systems – suitable for aerating nutrient reservoirs, DWC systems and other growing setups.

What is a 6 way airline manifold used for?

An airline manifold divides the output from one larger air supply into several smaller feeds. With six 4mm outlets available, this manifold makes it possible to supply multiple air stones or other aeration devices from one suitable air pump or compressor.

It is particularly useful when aerating larger nutrient reservoirs or when one air pump needs to serve several pots, tanks or growing positions.

How to use the 6 Way Plastic Airline Manifold

Connect the 8mm inlet to the main airline from a suitable air pump or compressor. Attach individual 4mm airline runs to the six smaller outlets, then route each line to the required air stone, diffuser or aeration point.

Keep the airline runs tidy and avoid unnecessary bends or restrictions. The amount of air delivered through each outlet will depend on the output of the connected pump, the number of outlets in use, airline length and the resistance created by the connected air stones or diffusers.

This type of manifold can also be used for distributing nutrient solution in suitable NFT installations where its connection sizes and flow characteristics are appropriate for the system.

6 Way Plastic Airline Manifold FAQs

What does a 6 way airline manifold do?

It takes one larger air supply and divides it between six smaller airline connections, making it possible to operate multiple aeration points from one suitable air pump or compressor.

What size connections does the manifold have?

The manifold has one 8mm inlet and six 4mm outlets.

How many air stones can I connect?

There are six individual outlets, allowing up to six separate airline runs to be connected. How many air stones can be operated effectively will depend on the output and pressure of the air pump being used.

Can I use this manifold with a hydroponic air pump?

Yes. It is designed for splitting airline from a suitable larger air pump or compressor and is well suited to hydroponic aeration systems.

What size airline connects to the outlets?

The six outlets are 4mm, making them suitable for compatible 4mm airline used with hydroponic air stones and aeration accessories.

Can the manifold be used in a DWC system?

Yes. It can be used to distribute air to multiple air stones in DWC and other hydroponic systems where additional nutrient solution aeration is required.

Can this manifold distribute nutrient solution as well as air?

Yes. Although commonly used as an airline splitter, this manifold can also be used to distribute nutrient solution in suitable NFT systems.

Does the manifold control the airflow to each outlet?

No. This plastic manifold acts as a simple distributor and does not have individual airflow control valves on each outlet.
