Oxygen Regulator for Disposable Oxygen O2 Cylinders (M12 Thread)

Pure oxygen is the best way to get your yeast off to a cracking start.  Simply use this high pressure and high capacity disposable tank to boost dissolved oxygen levels in your cooled wort.

Oxygen is great for use with high gravity beers or pilsners where you are trying to build up a large population of yeast.

We would recommend the use of a .  These small diffusion stones create very fine bubbles of oxygen in your wort and help the oxygen to dissolve into solution faster.  If you want a really nice option we would recommend the use of this  and this is a bit more ergonomic as you have a rigid stainless tube to force the stone to the bottom of the fermenter rater than it floating to the surface.

This regulator is designed to suit this that can be purchase separately. To avoid the chance of leaks and returning to an empty bottle, please triple check every connection point on your system or disconnect your gas cylinder between uses.
KegLand makes no guarantee it will suit other oxygen M12 cylinders on the market as this regulator was specifically designed for our branded s. Other cylinders may have different pin depths. 

Instructions
Attach the regulator to to the top of your disposable cylinder.  Turn pressure up to 10-20psi.  Immerse diffusion stone in wort for 1-2 minutes.
NOTE: Wort must be cold.  It is extremly difficult to get oxygen to dissolve into hot wort so it's essential to cool wort completely before starting this process.
