Description

The humble plastic ball lock disconnect has been around a long time and is used by countless homebrewers around the world.  Despite the extensive use they have seen little to no innovation for decades and KegLand wanted to change this. Enter the Duotight Ball Lock QD. The integrated Duotight design means you can connect your beer and gas line directly, easily and reliably with no need for additional fittings or clamps. It is a robust and super compact design that is incredibly easy to assemble and disassemble, making cleaning and sanitizing an absolute breeze!

Made from highly chemical resistant materials with stainless springs and ball bearings (no cheap ABS plastics here) this baby is extremely resistant to commonly used chemicals such as phosphoric based sanitizers and caustics. The incredibly small form factor allows for easy stacking of kegs. The new cap design ensures a pressure seal with just hand tightening and it can be completely taken apart for cleaning with no tools required.

This particular ball lock disconnect has been designed for use with EVABarrier 8 mm OD Tubing (D1717 & D1718). Due to the integrated Duotight fitting the line will simply push directly into this fitting.

Duotight Push-to-Connect
These Duotight ball lock disconnects already have the Duotight fitting built into the ball lock disconnect. No need for additional threaded fittings. Simply push the beer/gas line in and you are done!

Compact
The world's most compact ball lock disconnect ever manufactured. This new compact form factor is great for tight spaces or fridges where you want to pack as many kegs in as possible. This is one of the only ball lock disconnects that allows standard ball lock kegs to be double stacked while still connected to beer and gas lines.

Overmolded Poppet
The overmolded poppet design means you can couple and disconnect this ball lock QD under extreme pressures of up to 150 psi (higher than most kegs working pressure) and will never have issues with the o-ring blowing out.

Tool-less Disassembly
Other ball lock disconnects require a tool such as a flat head screw driver or spanner to take them apart for cleaning. The new caps on these allow for easy disassembly by hand, making these easier to break down for cleaning. It's literally never been easier to remove hop particles from your ball lock disconnects.

Extreme Chemical Resistance
No cheap ABS plastic or nitrile seals. This ball lock disconnect is made from stainless spring and ball bearings, with an engineering polyketone resin body, EPDM and PP/EPDM overmolded poppet. This makes the quick disconnect resistant to extreme chemicals such as phosphoric and acetic acid, caustic soda, peroxide and many other acid or base chemicals which are commonly used in homebrewing.

Toughness
This ball lock disconnect is more robust than any other plastic ball lock disconnect ever manufactured due to the use of new engineering plastics. Don't be fooled by the small form factor — these bad boys are tough!

High Flow
The internal design of these allows for faster flow meaning you can slightly quicker transfers when compared to other plastic ball lock disconnects.

Use Kegland duotight fittings and this eliminates a connection.

Can I use these on a standard corny keg?
Rick Roberts on May 20, 2022
BEST ANSWER: Yes. They can be used on any ball lock style keg (not pin lock).
I recently bought 39ft EVAbarrier 4mmx8mm. The first couples of feet fit perfectly with my 8 mm duo tight ball lock, but I notice that the rest of the tube is wide. And makes difficult to fit in with the rest of the connections. Does anyone have any advice?

BEST ANSWER: For me the tubing connectors on both the gas and liquid ball lock disconnects is ridiculously tight. To get the tubing to fully engage is a struggle and getting them out is very difficult - especially with the hard walled short connectors. I don't think the issue is your tubing. I think the engineering on these disconnects is just a bit too small. I love them for their profile, but I know I'm going to have a battle when I need to reconfigure them.

A Simple Connection Made Better
Honestly, I didn't think a standard ball lock fitting could ever be made better, but the duo-tight connection knocked this one out of the park! No tools necessary. which is a nice bonus.
