#7 Dual-Hole Silicone Carboy Bung & Stopper
Elevate your fermentation setup with our specialized #7 dual-hole silicone stopper. Designed specifically for standard 5-gallon (20L) glass carboys, this "Dual-Port" bung allows you to manage multiple fermentation tools simultaneously without compromising your airtight seal.
Whether you need to monitor internal temperatures while venting gas or set up a customized blow-off and racking system, this premium food-grade stopper provides the versatility professional and hobbyist brewer's demand.
Product Features:
Dual-Port Design: Features two precision molded holes—one 1 cm (approx. 3/8") and one 0.5 cm (approx. 13/64").
The 1 cm hole is perfectly sized for standard S-shape or 3-piece airlocks.
The 0.5 cm hole provides a snug, airtight fit for stainless steel thermowells, thin probes, or gas-in needles.
Airtight & Slip-Resistant: Unlike standard rubber stoppers that can become slippery when wet, our high-quality silicone grips the glass for a secure, "no-slip" seal that won't pop out during active fermentation.
Premium Food-Grade Material: 100% BPA-free, food-grade silicone that is odor-neutral and won't absorb flavors. Heat-resistant and exceptionally durable for years of use.
Built for Versatility: Beyond carboys, the flanged #7 design fits perfectly in 1.5" tri-clamp ferrules, ensuring the bung won't be "sucked" into the vessel during temperature drops or cold crashing.
