These acetal adapters with silicon o-rings are custom made and CNC cut for us by an engineering firm in Sydney.
They allow any of our mini keg tapping systems to be used with our insulated growlers.
These will only work with wide mouth threaded top growlers, not swing top growlers.
The adapter reduced the size of the mouth down to a 35mm wide thread so you can attached a picnic tapping system or a double ball lock top, or a full Pro Tapping System with bar tap and mini co2 regulator.
These are already included if you are buying a package deal with a growler and a tap system so you don't need to add one if this is the case.
Hi, What width opening is this designed for? I have an existing insulated growler and was looking for a tap setup. Thanks
Our growlers have a 53mm opening. If your growler is 2L or 4L and looks like ours and is a screw top then these adapters should fit. Feel free to send through an image if you like and I can confirm.
