Silicone Whiskey & Scotch Barrel Stoppers for Your Distillery

Our whiskey barrel bungs are easy to hammer in and remove, but still fit snug inside the barrel to prevent any leaks. They are designed with a lip that creates a tight seal and inhibits the bung from falling inside, even as the barrels are rolled around.

Additional benefits of whiskey & scotch barrel bungs:

  • Highly malleable
  • Superior durability
  • Available in custom colors & sizes
  • Available in a range of styles

Why Choose Silicone Bungs for Whiskey & Scotch Barrels?

Different from traditional wooden barrel bungs, our silicone bungs can be reused over and over again without any loss of sealing power and offer better resistance to odors and mold. As a non-reactive, stable material, silicone can withstand the high levels of ABV that whiskeys typically reach during maturation.

FDA-Approved Silicone Whiskey Barrel Plugs in Bulk

Our standard whiskey and scotch barrel bungs are manufactured in a translucent white color and available in standard U.S./French barrel sizes (55mm top x 44mm base x 48mm height). We also offer custom whiskey barrel bungs in the size, color, and/or logo you require. Request a quote to discuss your custom barrel bung specifications.
