duotight 6.35mm (1/4) Ball Lock Disconnect (Black + Yellow Liquid)
This next-generation Duotight Ball Lock Disconnect sets a new standard for homebrewing connections. Featuring an integrated Duotight push-in fitting, it allows you to connect 8 mm beer or gas line directly—no clamps, no extra fittings, no hassle.
Designed for maximum convenience and performance, this disconnect combines a super compact form factor, tool-less disassembly, and high chemical resistance, making it one of the most advanced quick disconnects available today.
The compact design makes it perfect for tight kegerator setups and even allows kegs to be stacked while still connected, something traditional disconnects struggle with.
Unlike older designs, this unit is built from high-performance engineering materials, including stainless steel springs and ball bearings, ensuring durability and resistance to common brewing chemicals such as phosphoric acid, caustics, and sanitisers.
