Dual-Hole Rubber Stopper for Airlock and Thermowell

Dual-Hole Design for Precise Fermentation Monitoring

Our Dual-Hole Silicone Stoppers are the perfect solution for brewers looking to streamline fermentation monitoring and airflow management. Designed with two pre-drilled holes of different diameters, these stoppers are ideal for securely fitting both an airlock and a thermowell simultaneously.

The dual-hole design allows you to maintain proper fermentation conditions by venting CO2 through the airlock while accurately monitoring the temperature of your fermenting wort with a thermowell. The snug fit ensures an airtight seal, making these stoppers essential for homebrewing or small-batch fermentation setups.

Key Features:

• Dual-Hole Design: Accommodates an airlock and thermowell for optimal fermentation management.
• Secure Fit: Creates an airtight seal to protect your fermenting wort.
• Versatile Compatibility: Fits standard vessels requiring #6.5 or #10-sized stoppers.
• Durable Material: Made from high-quality silicone for a reliable and long-lasting solution.

Upgrade your brewing setup with our Dual-Hole Silicone Stopper and achieve precise control over your fermentation process.
