These silicone bungs do not perish or leach chemicals or aromas like rubber bungs.

They are made with food grade silicone and can handle temperatures up to 180C. They also have excellent chemical resistance to a wide range of acid and alkaline cleaners and sanitisers.

We have a wide range of silicone bungs available, either solid or with an 8mm bored hole suitable for an airlock or blow off tube.
