Ideal for Fermenting Vessels

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.

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.

These Grommets are suitable for a standard Airlock and create an airtight seal. Could be used for other applications.

Each order is for 3 Grommets. ie. if you make a purchase of 2 you will pay £1.98 and receive 6 Grommets.

Postage is the same no matter how many packs of 3 Grommets are purchased.

Dimensions:
17mm (grommet width)
12.5mm (drill hole size)
9.5mm (hole for airlock)
1.6mm (grove depth around grommet)

P&P FOR UP TO 10 PACKS OF GROMMETS IS ONLY £0.99!
