Grommets are ideal for fermenting vessel lids when airlocks are needed
An ideal replacement for old grommets which may have perished over time preventing a tight seal. Grommets with signs of perishing should be replaced to avoid the possibility of contamination.
If you have a Fermenting Bin without a hole in the lid then you may wish to drill a hole to enable the use of an Airlock to allow CO2 to vent out and to prevent a lid without hole from being forced off.
These Grommets are suitable for a standard 6 chamber airlock and create an airtight seal.
Dimensions: 23mm (grommet width) 12.5mm (drill hole size) 9.5mm (hole for airlock)
