Silicon Bung 47-58mm – Solid

Silicone Bung 47-58mm – Solid

These pure silicone bungs are solid and designed for sealing demijohns, barrels, or fermenters with a secure, airtight fit. Made from high-quality food-grade silicone, they are durable and resistant to perishing, cracking, or absorbing odors, unlike traditional rubber bungs. Their temperature resistance of up to 180°C makes them ideal for a variety of fermentation and brewing applications, while their excellent chemical resistance ensures compatibility with a wide range of acid and alkaline cleaners and sanitizers.

Bored Bung 47-58mm – Fits 54L Glass Demijohns

Similar to the solid version, these bored silicone bungs are designed to fit 54L glass demijohns, providing a reliable and chemical-resistant seal. The bored hole allows for the easy insertion of airlocks or tubing, making them perfect for fermentation setups requiring controlled airflow. Crafted from food-grade silicone, they are non-permeable, heat-resistant (up to 180°C), and do not leach chemicals or odors, ensuring a clean and uncontaminated brewing process.

Both options are essential for homebrewers and winemakers, offering a long-lasting, high-quality alternative to rubber bungs for sealing and fermentation needs.
