Kit of 5+5 food grade silicone O-rings to replace the o-rings of the gas or liquid male ball-keg connectors. Generally the o-rings supplied with the ball-keg couplings are of poor quality, inhomogeneous shape, poor quality nitrile rubber therefore the seal is not guaranteed especially after several hooking-unhooking. If you check, the inside of the female connector turns black, that's rubber from the o-ring!

In the photos of the product you can appreciate the difference in shape by microscope comparing the BacBrewing red silicone o-ring with the black o-ring of a male connector that has never been used.

Also in the photos you can see the inside of a female connector ball keg used with the original black o-ring. You can see the black and more zoomed rubber fibers of the o-ring flaking off. That rubber, before the connector is fully coupled, comes into contact with the beer and is sucked in ...... de gustibus!

A syringe containing 2ml of FDA-certified food grade grease is also supplied to slightly lubricate the o-ring and facilitate coupling.

Lubricate only the external o-ring
