#9 Silicone Bung / Stopper for small 9 gallon (34 L) demijohn & small wood barrels
Our #9 Silicone Bung provides a professional-grade, airtight seal for your small-batch aging program. Precision-molded to fit the 1 1/2" bungholes common on small whiskey and wine barrels, as well as the specialized necks of 34L demijohns, this stopper ensures your vintage is protected from oxidation.The high-purity USA-made silicone is non-porous and odorless, guaranteeing no flavor transfer even during long-term maturation.
Ventilator: Features a unique 5-hole vent design that acts as a self-gassing airlock, releasing CO2 while maintaining internal pressure to prevent carboy cracking.
Grab Ring: Equipped with a reinforced top lip for effortless removal from tight-fitting oak staves.
Hole: Pre-drilled with a 25/64" (9.92 mm) opening to accommodate standard fermentation airlocks.
Superior Durability: Crafted from 100% food-grade white silicone that is heat-resistant and easy to sanitize, outlasting traditional rubber stoppers across multiple batches.
Airtight Hermetic Seal: The non-slip taper creates a deep friction lock, essential for the delicate aging and "topping off" phases.
