The duotight Bottle Filler Beer Gun Gen2 is a practical keg-to-bottle filling tool designed for home brewers who want to bottle beer from a keg with speed, control, and reduced oxygen exposure. If you already have beer on tap but want to take bottles to a game, beach day, barbecue, party, or friend’s house, this beer gun makes the job much easier.
Fill Bottles Directly From a Keg
Bottling from a keg can be difficult without the right equipment. Foaming, oxygen exposure, and inconsistent fills can all affect the final result. Therefore, the duotight Bottle Filler Beer Gun Gen2 gives brewers a cleaner and more controlled way to fill bottles from carbonated beer.
This unit includes both gas and liquid triggers. As a result, you can purge the bottle with CO2 before filling, then dispense beer into the bottle with greater control.
Helps Reduce Oxidation
Oxygen can quickly damage beer flavour, aroma, and freshness. Because this bottle filler includes a CO2 purge function, it helps remove oxygen from the bottle before beer is added. In addition, the CO2 jacketing tube helps improve bottle purging during the filling process.
This makes the duotight Bottle Filler Beer Gun Gen2 especially useful when bottling hop-forward beers, lagers, pale ales, IPAs, and other styles where freshness matters.
Easy duotight Setup
This Gen2 version includes duotight fittings as standard. Consequently, setup and pack away are faster, more secure, and easier than older bottle filler systems that rely on clamps or more complicated fittings.
The included duotight liquid ball lock disconnect, gas carbonation cap fitting, EVABarrier hosing, and duotight compression elbow give brewers the parts needed for a clean and simple kegging connection.
Stainless Steel Beer Contact Parts
Every part that comes into contact with your beer is stainless steel. This helps maintain clean flavour and improves durability during regular use. The silicone tip also helps create smooth filling contact at the bottom of the bottle.
Unlike some counter-pressure fillers, the duotight Bottle Filler Beer Gun Gen2 does not require a pressurising stopper. Therefore, you can fill bottles of different depths without buying different stem lengths or adding plastic hose extensions.
Whether you are preparing bottles for sharing, travel, tastings, competitions, or storage, the duotight Bottle Filler Beer Gun Gen2 is a reliable tool for bottling beer from your kegging system.

Benefits for Home Brewers
Bottle Beer From Your Keg
This beer gun lets you fill bottles from kegged beer without needing to transfer the entire batch. As a result, you can keep beer on tap and still take bottles with you.
Helps Protect Beer Freshness
The CO2 purge helps reduce oxygen inside the bottle before filling. This can help protect flavour, aroma, and shelf life.
Fast and Secure duotight Connections
The included duotight fittings make setup simple. They also create a secure push-in connection for compatible tubing and kegging hardware.
Stainless Steel Beer Contact
Beer contact parts are stainless steel, which helps maintain clean flavour and supports long-term durability.
No Pressurising Stopper Required
Because this filler does not rely on a pressurising stopper, it can fill bottles of different depths more easily.
How It Works
- Connect the liquid line from your keg to the beer gun.
- Connect the gas line for CO2 purging.
- Insert the filler into a clean and sanitised bottle.
- Use the gas trigger to purge the bottle with CO2.
- Use the liquid trigger to fill the bottle from the keg.

For best results, chill bottles before filling and keep beer cold to help reduce foaming.
