There are several types of Ball Lock keg available, including standard stainless 19L and 9.5L Cornelius Kegs, stainless Mini Kegs and also OXEBAR kegs in 20L, 8L and 4L sizes. If using Mini Kegs or 4L or 8L OXEBAR Kegs you will also need a ball lock tapping head.

To carbonate and dispense from a homebrew style keg you will need to use disconnects. These come in two different categories which are specific for ball-lock or pin-lock kegs. Balllock kegs require ball-lock disconnects and pin-lock kegs require pin-lock disconnects

Each keg requires a liquid disconnect (black) and a gas disconnect (grey). Due to the design of the posts on the keg a liquid disconnect can only be used on the black liquid (OUT) post and a gas disconnect can only be used on the grey gas (IN) post.

Inserting EVABarrier hose into duotight fittings

Before connecting EVABarrier to duotight push fittings, ensure that the EVABarrier is cut at a straight and clean right angle using a sharp utility knife or (ideally) a KL07689 Tube Cutter

If the EVABarrier has been used previously, it is a good idea to cut off 20mm or so as the end may be marred from the teeth in a duotight collet.

Gen 3 duotight fittings are marked with a depth indicator. You can hold the EVABarrier against the fitting up to the line and make a small mark to ensure you have fully inserted the EVABarrier into the duotight fitting. The EVABarrier must be inserted deeply enough that it is engaged by both internal o-rings - approximately 22mm.

Once inserted, pull on the EVABarrier to ensure it is secure. If it comes out easily please follow the above steps again to ensure a good, tight, secure fit.

To remove EVABarrier from a duotight fitting, push down on the collet of the duotight fitting. The correct sized notch in a 7 in 1 tool is ideal for this as the collet needs to be held down concentrically.

While holding the collet down, simultaneously pull the EVABarrier out of the fitting.

Once the hose is removed cut the burred end off with a tube cutter or Stanley knife to produce a clean straight cut, this aids with forming an airtight seal.

Prior to attaching the keg coupler onto the keg make sure that a gas line is connected to the gas inlet and this gas line is connected to a regulator and a beer line is connected to the liquid outlet and this beer line is connected to a tap. Attaching the keg to the keg coupler is usually the last step of the kegerator setup.

A-Type Keg Coupler

Slide the keg coupler over the groove on the top of the keg then firmly depress the handle to tap the keg. NOTE: To fit a 50L keg with an A-type keg coupler into a kegerator or if your keg is a DIN style keg (tall skinny style) you will need to use a KL00390 Low Profile Elbow Bend

D-Type and S-Type Couplers

Push the coupler into the opening of the spear and then rotate firmly clockwise to attach the coupler to the spear. Then firmly depress the handle to tap the keg.

NOTE: duotight collets are colour coded to represent the appropriate EVABarrier tubing diameter. 6.35mm collets are green, 8mm are black and 9.5mm are blue

KegLand Commercial Couplers are supplied with duotight fittings that make connecting EVABarrier gas and beer line quite easy.

However, if you plan on switching couplers or wish to use an alternative connection method that allows a bit more customisation, we recommend replacing the duotight fittings with Ball Lock Posts. When adding Ball Lock Posts to a coupler setup, it is recommended to also add a KL00390 which will make it easier to fit a 50L keg.

You will also need a KL00840 and a KL00833 which will replace the duotight fittings on the coupler and allow you to use Ball Lock Disconnects on the beer and gas line instead

When setting up a kegerator system at home, it is important to understand the differences between the two main types of keg on the market.

The different kegs require different gas and beer line fittings inside the kegerator. Other components of the kegerator (taps, font etc) are interchangeable. The way in which the beer line and gas line is attached to the keg is the main point of difference.

We divide kegerators into two types: setups and setups. Kegs in both types are available in multiple sizes.

It is possible to mix and match keg styles in the one kegerator, provided the kegs are small enough to fit. Simply use the correct connection (coupler or ball lock disconnects) on ach beer and gas line to allow this.

For example, you may wish to have a on tap, as well as in a 19L keg. In that case, one beer/gas line would be terminated with an A Type Coupler, and the other would have a gas and a liquid ball lock disconnect.
