The duotight 9.5mm x Ball Lock Disconnect Black + Yellow Liquid is a premium liquid ball lock disconnect designed for brewers who want a faster, cleaner, and more reliable kegging connection. With an integrated duotight fitting, this disconnect allows compatible beer line to push directly into the fitting with no clamps or extra threaded parts required.

Integrated duotight Push-In Connection

Traditional ball lock disconnects often require additional fittings, clamps, or threaded adaptors. However, the duotight 9.5mm x Ball Lock Disconnect Black + Yellow Liquid has the duotight fitting built directly into the disconnect body. As a result, setup is quicker, neater, and more secure.

This model is designed to suit 9.5mm OD beer and gas line, including larger EVABarrier line commonly used in fast-flow transfer kits. Simply cut the line square, push it firmly into the fitting, and the double O-ring system creates a tight seal.

Compact Design for Tight Keg Setups

Space inside kegerators and keezer setups can be limited. Therefore, this compact ball lock disconnect is ideal for tight spaces where standard fittings can be bulky. Its small form factor can help make keg stacking and line management easier.

The black and yellow liquid colour coding also makes it easy to identify your beer line connection. This helps reduce confusion when working with multiple kegs, transfer lines, or liquid posts.

Built for Cleaning and Durability

The duotight 9.5mm x Ball Lock Disconnect Black + Yellow Liquid is made from highly chemical-resistant materials, including a polyketone body, stainless steel springs, stainless ball bearings, and quality seals. It is resistant to commonly used brewing chemicals such as phosphoric-based sanitisers and caustic cleaners.

In addition, the cap design allows tool-less disassembly. This makes cleaning and sanitising much easier, especially when hop particles, yeast, or beer residue enter the disconnect. Because it can be taken apart by hand, maintenance is fast and simple.

Generation 2 duotight Performance

Generation 2 duotight fittings are designed for excellent sealing performance. They use a double O-ring system with EPDM and silicone seals. EPDM offers strong gas and chemical resistance, while silicone performs well in cold temperatures.

This design provides more sealing surface than standard single O-ring push-in fittings. Consequently, it helps reduce the chance of leaks, even when the line is bent in a tighter radius.

The duotight 9.5mm x Ball Lock Disconnect Black + Yellow Liquid is a strong choice for home brewers who want a compact, high-flow, easy-cleaning liquid disconnect for kegging and transfer applications.

Benefits for Brewers

Easy Push-In Connection

The built-in duotight fitting allows compatible line to push directly into the disconnect. Therefore, setup is fast and simple.

No Clamps Required

The double O-ring sealing design removes the need for hose clamps. This creates a cleaner, more compact kegging setup.

Compact Kegerator Fit

The small form factor is ideal for fridges, kegerators, and tight keg spaces. It can also make keg stacking easier.

Easy to Clean

The cap can be removed by hand with no tools required. As a result, cleaning hop particles and beer residue from the disconnect is much easier.

Reliable Sealing Performance

The EPDM and silicone double O-ring system helps reduce leaks and improves performance in cold brewing environments.

Strong Chemical Resistance

This disconnect is built from materials designed to handle common brewing cleaners and sanitisers, including phosphoric-based sanitisers and caustic solutions.

Compatible Tubing

This disconnect is designed for 9.5mm OD line, including:

• EVABarrier 6.3mm ID x 9.5mm OD Double Wall EVA
• Black Lightshield EVABarrier 6.3mm ID x 9.5mm OD Double Wall EVA
• Other compatible 9.5mm OD beer or gas line

For best results, cut the tubing straight and fully insert it into the duotight fitting.

Ideal Applications

• Beer Line Connections
• Liquid Ball Lock Keg Connections
• Keg Transfers
• Fast Flow Transfer Kits
• Kegerators
• Keezers
• Home Brew Kegging Systems
• Cornelius Kegs
• Ball Lock Keg Setups
• Compact Keg Storage
• Cleaning and Transfer Lines

Generation 2 duotight Features

• Colour coded collets
• 9.5mm / 3/8″ fittings use blue collets
• Burst pressure over 300psi at 25°C
• Polyketone material instead of acetal
• Higher chemical resistance
• Improved UV resistance
• Excellent gas barrier performance
• EPDM and silicone seals
• Strong cold temperature performance
• Gauge depth indicators for easier fitting

Why Double O-Rings Matter

duotight fittings use a double O-ring sealing system for improved reliability. The two O-rings provide extra sealing surface compared with single O-ring fittings.

EPDM offers strong gas and chemical resistance. Silicone also resists chemicals and performs well in colder conditions. Together, these seals help create a more secure connection and reduce the chance of leaks.

This design also allows the hose to bend in a tighter radius with less risk of leaking.

How to Use

1. Cut your 9.5mm OD beer line straight, not on an angle.
2. Push the line firmly into the duotight fitting.
3. Check the depth indicator to ensure correct insertion.
4. Connect the disconnect to the liquid post on your ball lock keg.
5. To remove the line, push in the collet and pull the hose out.

If your beer line is pulled sideways often, consider using a duotight male-to-female elbow. This can allow the line to swivel and reduce kinking.
