Frequently asked questions about the D21-27 silicone bung
How do I find the right size?
Measure the inner diameter of the opening. The bung fits when it is between 21 and 27 mm, so the bung goes some way into the opening and seals well.
Do standard airlocks fit the hole?
The hole is 9 mm, which is a common size for airlocks. Still, check the stem diameter of your airlock.
Why silicone rather than rubber?
Silicone handles heat and sanitisers well and does not give off flavour. The bung is easy to clean and can be reused.
