Silicone Bung Bored Fits 3L & 5L Erlenmeyer

This Silicone Bung 32 x 48 Bored is designed to upgrade your yeast propagation setup, providing a reliable and sanitary seal for large Erlenmeyer flasks. Manufactured from high quality food grade silicone using lead free curing, it is fully safe for brewing use and resistant to chemicals, ensuring no unwanted flavours or contaminants affect your yeast cultures.

With a tapered design from 32mm to 48mm, this bung is specifically sized to fit 3L and 5L Erlenmeyer flasks. The pre drilled hole allows for easy fitting of a standard 3 piece airlock or a blow off tube, making it ideal for active fermentations and yeast starters where gas needs to escape safely.

The flexible silicone construction ensures a tight seal while remaining easy to insert and remove. It is well suited to brewers looking to maintain clean, controlled conditions when building yeast starters or conducting small scale fermentations.

Please note this bung is not designed for use with carboys or demijohns and is intended specifically for Erlenmeyer flasks.
