Do you want fresher beer for longer in your mini keg? Then you need to replace those green or black o-rings with the KegLand Yellow Low2 O-rings.Dimensions:29mm (ID) x 35mm (OD) x 3mm (thickness)

What is Low2?

Low2 O-Rings are the new golden yellow standard of homebrew kegs brought to you by KegLand Australia. 

Why? 

Because of their unique composition (Synthetic M-Class and Cross-Linked Elastomers), they have superior oxygen barrier properties than that of the previus O-Rings (Silicone). This results in your beverage staying fresher for longer.
