Product Highlights

Australian Made and individually tested, our King Kegs are the packaging solution that puts safety, reliability and affordabilty back into the keg market.

Our unique, patented manufacturing process produces a 20 litre vessel with integrated handles for easy transport.

The King Keg's unique P.E.T. material will keep beverages light safe while the keg's active oxygen scavenger keeps beverages fresh for up to 18 months.

The Ball Lock variety King Keg comes complete with a rigid dip tube that will need to be installed by the user when assembling the lid and post components.

The design of the Ball Lock variety King Keg differs slightly from the A and D type varieties and is not stackable.

The Ball Lock variety has a Pressure Relief Valve (PRV) located on the lid assembly, not in the neck of the keg.

Polyethylene terephthalate, also called PET, is the name of a type of clear, strong, lightweight and 100% recyclable plastic.

PET is a byproduct ("waste product"), derived from crude oil and natural gas during petrol processing when refining oil into petrol for cars. Unlike minerals such as steel or glass, it is not purposely dug for into the ground via giant mines that are ecologically damaging the environment, including the use of massive amount of chemicals to make refining raw steel into usable steel.

PET is a very energy efficient packaging material in comparison to glass, aluminum and other materials used for similar containers.
