## Questions & Answers

**Q: what size of hole do these fit?**
A: I don't know, but they're the standard size for the pre moulded holes in standard rubber bungs. I don't have one to hand but I'd estimate about 10mm in diameter. If you have a solid rubber bung, you'd be able to drill it to suit.

**Q: what do airlocks achieve?**
A: Airlocks allow the carbon dioxide created as a byproduct of fermentation to escape from the fermentation vessel, without allowing the air from the outside to enter the vessel, spoiling the product. The airlocks are filled with water and the pressure inside the vessel is great than outside as the Co2 is created and this bubbles through the water to escape.

**Q: Hi if i shape the bung to fit can these be used with a  25 ltr bucket?**
A: Hi Yes this is what i do for the initial fermentation

**Q: Are these to fit demijohns?**
A: The bungs that are supplied with the airlocks will fit into 1 gallon glass demijohns. The airlocks can be pushed into the grommets of 1 gallon plastic demijohns.
