DRY AIRLOCK.
This silicon dry airlock removes the use of a liquid airlock.
No more liquid being sucked back into the fermenter.
I have used these for many years without fault.
As seen in the image the center silicon flap forms a seal over the escape holes and only opens to release CO2 when pressure builds inside the fermenter.Second bung for illustration purposes only.
The bung has a taper from 28-34mm and requires you drill a hole to fit.
Shipping weight 30gm.
