Airlocks and Bungs

These are designed to fit the most common sizes. They are an essential part of your home brew equipment!

They are essential pieces of homebrew kit and do need replacing fairly often.

So, we 've given you a discount if you buy bulk! We are nice people!

Some old homebrew books recommend that you put steriliser in the airlock, we never bother, it gets blown out by the gas anyway!

Put a bit of water in the airlock and leave it alone, it should be obvious when it bubbles!

Don't confuse our bungs with those that footballers get, we'd never influence the outcome of the FA Cup. Unless Stockport County were in the final of course....

Fits most demi johns, if you have the old screw neck ones you might find they're too big.

I don't like to say this but you're probably better throwing the old screw neck demi johns away!

Plastic Bubbler Type Airlock

The most popular type of airlock and give a nice "plop" sound as they bubble!

Two Piece Airlock

These are cheaper but the top bit tends to get lost and they seem to dry out quicker than the bubbler.

Rubber Fermenter, Carboy, Demijohn caps

Rubber caps to fit fermenters, water bottles, carboys and all many of things. Mainly for glass carboys but fit plastic ones as well.

s'll want the 50mm one for those water bottles out of the cold water machines.

Come in three sizes, they stretch quite well. The 50 mm will fit up to a 70mm neck glass carboy at a stretch. So theres a decent overlap on the sizes. The 60mm rubber cap fits the 70mm carboy much better!

Safety Corks

Used to be called the dry airlock. Ok for short term storage, they don't dry out and let any gas out if the wine starts fermenting again.

Spare Bung For Betta Bottle

Rubber Grommet To take an airlock

Small red rubber grommet. Takes a standard airlock. You can drill a 13 mm hole in a cap and it will then take this grommet!

An easy way to convert those gallon water bottles from Tesco...
