Series 4 User Guide | Homebrew/Cornelius Kegs & Disconnects
There are two different styles of Cornelius kegs: Ball Lock and Pin Lock. Pin Lock kegs are not really in common use now. Any Cornelius style kegs purchased from KegLand will have Ball Lock fittings.
Ball Lock fittings can be identified by the posts on the keg or tapping head and require the use of Ball Lock Disconnects:
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.
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 froma 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.
