£1.25

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

This 8 Way Plastic Airline Manifold provides a simple way to distribute air from a single larger air pump or compressor to multiple air stones, air curtains or aeration points.

The manifold features one larger 8mm inlet and eight smaller 4mm outlets, allowing a single incoming air supply to be divided across several individual airline runs.

It is particularly useful in hydroponic systems, nutrient reservoirs and other growing setups where several pots, tanks or air stones need to be supplied from the same air pump.

Why use an 8 Way Airline Manifold?

  • Eight separate air outlets – split one air supply across multiple aeration points.
  • 8mm inlet connection – designed to connect to a larger main airline from a suitable air pump or compressor.
  • Eight 4mm outlets – suitable for standard 4mm airline used with air stones and other aeration accessories.
  • Ideal for multi-pot systems – distribute air neatly to several reservoirs, pots or growing positions.
  • Simple system layout – reduces the need for multiple individual pump outlets and keeps airline runs organised.
  • Suitable for hydroponic aeration – useful for supplying air stones and air curtains in nutrient reservoirs and other growing systems.

What is an 8 way airline manifold used for?

An airline manifold takes the output from one air pump or compressor and divides it into several smaller airline feeds. This allows multiple air stones, air curtains or aeration points to operate from the same main air supply.

The eight 4mm outlets make it particularly useful for larger hydroponic or irrigation setups where several reservoirs, tanks or growing positions require aeration at the same time.

How to use the 8 Way Plastic Airline Manifold

Connect the 8mm inlet to a suitable airline running from your air pump or compressor. Attach individual 4mm airline lengths to the eight outlet connections, then route each line to the required air stone, air curtain or aeration point.

Position the manifold where the airline runs can be kept tidy and as direct as possible. Keeping individual outlet lines reasonably similar in length can also help create a more balanced aeration layout.

The amount of air reaching each outlet will depend on the performance of the air pump, the number of outlets being used, airline length and the resistance created by the connected air stones or diffusers.

8 Way Plastic Airline Manifold FAQs

What does an 8 way airline manifold do?

It divides one larger air supply into eight smaller airline feeds, allowing several air stones, air curtains or other aeration points to run from the same air pump.

What size airline fits the manifold?

The manifold has an 8mm inlet for the main air supply and eight 4mm outlets for individual airline runs.

Can I use this manifold with air stones?

Yes. The 4mm outlets are suitable for running standard airline to compatible air stones and other aeration accessories.

Can I use this manifold in a hydroponic system?

Yes. It is well suited to hydroponic systems where one air pump needs to supply several reservoirs, pots or air stones.

How many air stones can one manifold run?

The manifold provides eight separate outlets, so it can supply up to eight individual airline runs. The number of air stones that can be operated effectively will depend on the output of the connected air pump and the resistance within the system.

Do I need a powerful air pump for an 8 way manifold?

The air pump needs to provide enough output for the number and type of aeration devices connected. Larger air stones, longer airline runs and multiple outlets will all increase the demand on the pump.

Can I use fewer than eight outlets?

Yes. You can run fewer than eight airline feeds if required. Any unused connections should be managed so that air is not unnecessarily lost from the system.

What can the 4mm outlets be connected to?

The 4mm outlets can be used with compatible airline feeding air stones, air curtains and other aeration accessories commonly used in hydroponic growing systems.
