#8 Silicone Bung / Stopper for larger carboys/small wood barrels
Ensure the success of your fermentation with our #8 Silicone Bung. Precision-molded for 5-gallon (20L) carboys and small wood barrels, this stopper provides a superior, airtight seal that prevents oxidation and spoilage. Made from high-purity white silicone, it is non-porous and odorless, guaranteeing that no unwanted flavors or contaminants will impact your wine, beer, or spirits during aging.
Advanced Ventilating Option: The specialized 5-hole vent design acts as a self-gassing airlock, allowing CO2 to escape freely while maintaining steady internal pressure to prevent carboy cracking or blowouts.
Multi-Configuration Tooling: Available as a Solid stopper for hermetic storage, Bored (with hole) for standard fermentation airlocks, or with a reinforced Grab Ring for effortless removal from tight-fitting oak staves.
Medical-Grade USA Silicone: Crafted from 100% food-grade silicone that is BPA-free and highly durable. It will outlast standard rubber stoppers and withstand repeated sanitization without degrading or losing its shape.
Superior Chemical Resistance: Stable and flexible across a wide temperature range, making it suitable for both cold storage and high-heat sterilization environments.
