It can hold Kombucha, cold coffee, soda, iced tea, soda, mimosa, spray blends and what you want any other beverage. You can fill the mini keg with your favorite beer so you can enjoy it at home or at any party.




(1) Since the 4L mini keg is integrally stretched, there are fewer solder joints, which are less likely to rust and breed bacteria.
(2) The 4L mini keg is subjected to a pressure of 200-300 PSI.
(3) The leak hole on the keg can ensure the smooth flow of beer, no easy rust.
(1) 16 g or 74 g of gas can be connected.
(2) The dial is not easy to break, the quality is better and more accurate.
(3) Because the hand wheel has threads, it can prevent hand slip.
(4) When the internal pressure reaches 1.8K, the 1.8K part has a decompression function to ensure safety. This is our special design.
(1) Sealability (Pull out the ball lock and the above parts without leaking).
(2) The spear is also connected to the plastic faucet, and the air intake part can also be connected to the atmospheric bottle to reduce the cost.

Trouble shooting | Solution |
Leaks gas as soon as the cartridge is installed | 1.Make sure the regulator dial is off turned all the way counter close 2.Tighten the cartridge seal Replace the CO2 cartridge it is damaged |
Make sure the CO2 cartridge is installed, the cap is turned on, and pressure is indicated on the pressure gauge. | |
without stopping when closed | 1.A few drips after closing the tap is normal. But it should not drip over time. 2. If the keg and tapping system is clean, internal O-ring may have worn through use and be in need of replacement. |
1.First pour may be foamy if the beer line is full of air after being filled or the tap assembly has been allowed to warm up. Second beer should pour fine, if that's the case. Keep out of the sun. 2.Beer may be highly carbonated from the bar or brewery. If beer in keg is pressurized at 5 psi but came from brewery beer line pressurized at 25 psi, beer will pour foamy until the pressure equalizes after few days in the keg. Be sure to open the tap handle fully and let go during the pour. Attempting to meter the flow during the pour can lead to foaming. |
