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.
Duotight Ball Lock QDs are offered in three sizes that correspond to the outer diameters seen on our line of EVABarrier Draft Tubing.
- 6.35 mm OD – features a very tight 3 mm ID that requires only 3.2 ft of length for adequate flow resistance. This is the ideal size for mobile draft or if you want to keep your kegerator as tidy as possible.
- 8 mm OD – the most common OD size of EVABarrier tubing. This size comes in two IDs (4 mm & 5 mm) and pairs up with the lion's share of Duotight fittings and accessories. 4 mm ID is our most recommended size for beverage lines, requiring 5-6 ft. lengths. 5 mm ID is commonly used as gas line or when 10-12 ft. beverage lines are required.
- 9.5 mm OD – suitable for gas lines or long draw beverage lines. At 6.3 mm ID, this size is ideal for beverage lines that will be 20 ft. or longer in length.
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.
