Guide to Commercial Kegs & Couplers

KegLand Undercover / Build In / Semi-Integrated Kegerator | Commercial Kegs & Couplers

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.

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.

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

Removing EVABarrier Hose from duotight fittings

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.

Using Ball Lock DIsconnects with Commercial Couplers

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 Low Profile Elbow Bend which will make it easier to fit a 50L keg.

You will also need a KL00840 Cornelius Type Ball Lock Post 5/8 Liquid and a KL00833 Cornelius Type Ball Lock Post 5/8 Gas which will replace the duotight fittings on the coupler and allow you to use Ball Lock Disconnects on the beer and gas line instead
