Gas Line Manifold Splitter 3 Way is a simple and practical way to divide one regulated gas supply across three separate keg lines. It is ideal for homebrewers running multi-keg kegerators, keezers, home bars or other draught systems where several vessels need to receive gas from one regulator.

The aluminium manifold body includes three individually controlled outlets. Each outlet uses a 1/4-inch threaded ball valve with a 6mm hose barb, allowing compatible gas tubing to be connected directly.

The manifold is rated to 100psi and is intended for gas distribution only.

Split One Gas Line into Three

A single regulator outlet can only feed one line unless a splitter, manifold or secondary regulator system is added.

This three-way manifold allows one incoming gas supply to feed:

• Three Corny kegs
• Three PET kegs
• Three pressure fermenters
• A combination of compatible gas-fed vessels
• Multiple gas lines inside a kegerator
• A small keezer or home bar system

All three outlets receive approximately the same inlet pressure unless additional pressure-control equipment is installed downstream.

Three Individual Ball Valves

The Gas Line Manifold Splitter 3 Way includes three ball valves, allowing each gas outlet to be opened or closed independently.

This is useful when:

• Disconnecting one keg
• Changing a keg
• Servicing a gas line
• Isolating an unused outlet
• Checking for leaks
• Running fewer than three vessels

Individual shut-off control makes the gas system easier to manage than a basic fixed tee splitter.

1/4-Inch Threaded Connections

The ball valves screw into the aluminium manifold using 1/4-inch threads.

This threaded design provides flexibility for users who want to replace or upgrade the outlet fittings.

Compatible alternatives may include:

• Replacement 1/4-inch ball valves
• Selected push-in fittings
• Ball lock gas posts
• Threaded adaptors
• Stainless joining nipples

Confirm thread compatibility before fitting any accessory.

6mm Hose Barbs

Each supplied ball valve includes a 6mm hose barb.

The barbs suit compatible gas tubing and should be secured with appropriate clamps where required.

For reliable installation:

1. Confirm the tubing’s internal diameter.
2. Push the tubing fully over the barb.
3. Fit a suitable clamp.
4. Avoid overtightening the clamp.
5. Pressure-test the connection.
6. Inspect it regularly for leaks.

Replace tubing that has hardened, cracked or become difficult to seal.

Rated to 100psi

The manifold is rated for gas pressure up to 100psi.

This rating provides capacity for many common kegging and dispensing applications. However, the maximum safe operating pressure of the complete system is determined by its lowest-rated component.

Always consider the limits of:

• Kegs
• PET vessels
• Regulators
• Gas tubing
• Disconnects
• Pressure relief valves
• Push-in fittings
• Other connected equipment

Never exceed the pressure rating of any connected part.

Gas Only

This manifold must only be used for gas.

It is not suitable for:

• Beer
• Cider
• Wine
• Water
• Soft drinks
• Cleaning solution
• Any other beverage or liquid

The internal check-valve and ball-valve components are intended for gas distribution rather than beverage contact.

Clearly label the manifold and lines to prevent accidental liquid use.

Check-Valve Pressure Drop

The manifold’s ball valves include check-valve mechanisms that create an approximate pressure drop of 2psi.

This means the pressure at the keg may be around 2psi lower than the pressure shown at the regulator.

For example, if the desired keg pressure is 12psi, the regulator may need to be set to approximately 14psi.

This is a general allowance. Actual pressure should be confirmed using your complete setup.

Check-Valve Benefits

The integrated check-valve mechanism helps reduce the risk of pressure or gas flowing backwards through the manifold.

This can be useful when connected kegs have different internal pressures.

However, check valves should not be treated as a complete substitute for:

• Correct pressure management
• Non-return valves where required
• Regular leak checks
• Proper regulator setup
• Suitable gas-line routing

Always keep liquid away from the gas system.

Expandable to Four Outlets

The manifold can be converted from three outlets to four by adding a compatible 1/4-inch ball valve.

The recommended accessory is:

• KL05173 – 1/4-inch ball valve

This provides flexibility if your system grows from three to four kegs.

Confirm that the spare manifold port and valve thread are clean and compatible before installation.

Optional Gas Ball Lock Post

A compatible gas ball lock post with a 1/4-inch bulkhead assembly may be fitted to the manifold.

This can provide a quick-disconnect gas inlet or outlet, depending on the installation.

Potential benefits include:

• Easier manifold removal
• Quick connection to an existing gas line
• Portable gas distribution
• Faster servicing
• Reduced need to remove tubing from barbs

Make sure the post is fitted securely and leak-tested.

Duotight Push-In Compatibility

The supplied barb fittings may also be replaced with compatible Duotight push-in fittings.

The suggested option is:

• KL06897 – Duotight 8mm to 1/4-inch push-in fitting

Push-in fittings can provide:

• Faster line installation
• Cleaner gas-line routing
• Easier tubing removal
• Reduced use of hose clamps
• Good compatibility with suitable EVABarrier gas tubing

Cut tubing squarely and push it fully into the fitting.

Joining Multiple Manifolds

Multiple manifolds can be joined using a compatible stainless steel hex nipple.

This may be useful for larger systems requiring:

• Six or more gas outlets
• Multiple keg banks
• Expanded keezer setups
• Large home bars
• Organised gas distribution

When joining manifolds, make sure the mounting surface can support the additional weight and that every threaded connection is sealed correctly.

Same-Pressure Gas Distribution

A standard manifold distributes approximately the same pressure to all open outlets.

This works well when all connected beverages require similar carbonation and serving pressure.

Examples may include:

• Three pale ales
• Three lagers
• Beer and cider at similar pressure
• Several kegs being carbonated together

For different pressure requirements, use secondary regulators or individual pressure-control devices.

Different Beverage Pressures

Some beverages need significantly different gas pressure.

For example:

• Sparkling water may require high pressure
• English ale may use lower pressure
• Cider may require moderate or high carbonation
• Pressure fermenters may use a separate pressure setting

A basic manifold cannot independently control each outlet.

Use a multi-output regulator, secondary regulator bank or compatible inline pressure controls when separate pressures are needed.

General Installation Guide

A typical installation process includes:

1. Secure the manifold to a suitable surface.
2. Connect the regulator gas line to the inlet.
3. Fit compatible gas tubing to each 6mm barb.
4. Secure each line with a suitable clamp.
5. Connect the gas disconnects or couplers.
6. Close all manifold valves.
7. Open the cylinder and set the regulator.
8. Open each outlet one at a time.
9. Check every connection for leaks.
10. Adjust the regulator approximately 2psi higher if required.

Follow the regulator and cylinder manufacturer’s instructions.

Mounting the Manifold

The manifold may be mounted:

• Inside a kegerator
• On a keezer collar
• Behind a home bar
• On a brewing wall
• Near a gas cylinder
• In a draught service cabinet

Choose a location that provides:

• Easy access to the valves
• Good visibility
• Protection from spills
• Secure mounting
• Neat tubing routes
• Space for future expansion

Avoid mounting it where beverage leaks could flow onto it.

Leak Testing

Gas leaks can empty a CO₂ cylinder quickly.

After installation:

1. Pressurise the gas system.
2. Apply a suitable leak-detection solution to each connection.
3. Check the inlet, valve threads, barbs and tubing.
4. Watch for bubbles.
5. Tighten or reseal leaking fittings.
6. Retest the complete manifold.

Never use a flame to search for gas leaks.

Maintenance

Inspect the manifold regularly for:

• Loose valve threads
• Leaking barbs
• Cracked tubing
• Worn clamps
• Sticking ball valves
• Damaged check valves
• Corrosion
• Physical damage

Replace faulty components promptly.

Do not lubricate gas components unless the lubricant is specifically approved for the fitting and gas service.
