37mm – 45mm Bored Silicone Bung

The 37mm – 45mm Bored Silicone Bung is made of a sturdy rubber composite. The bored hole allows for an airlock to be securely attached while maintaining an airtight seal. This silicone bung is the perfect fit for our 15l demijohn.

Regularly checking your fittings and seals will allow you to keep your vessel seals tight while also preventing leaks. For best results; we recommend that you check your vessel seals/fittings every 4-6 months, and replace major seals/fittings once per year.
