#12 Silicone Bung / Stopper for some S.S. Tanks and Kegs
Our #12 Silicone Bung is engineered for the rigorous demands of professional cellars. Designed specifically to fit the wider openings found on stainless steel tanks and modified kegs, this stopper provides a superior airtight seal. The premium food-grade silicone is non-porous and odorless, ensuring it will not absorb aromatics or harbor bacteria between batches, providing a significantly more hygienic seal than traditional rubber.
Oversized Tapered Design: Precision-molded to fit openings ranging from 54mm (bottom) to 63.5mm (top), ensuring a deep friction seal that won't slip under pressure.
Versatile Configurations: Available in Solid for airtight aging and storage, or Bored (with hole) to accommodate large-scale fermentation airlocks.
USA-Made Quality: Crafted from high-purity, BPA-free silicone that meets strict FDA food-safety standards—critical for commercial production and long-term maturation.
Heat & Chemical Resilience: Capable of withstanding repeated steam-sanitization and caustic cleaning without cracking or losing its elastic memory.
