Standard silicone whiskey barrel bungs with precision-molded 3/8” thru holes. These through holes are ideal for airlock devices/airlock functions and allow for the insertion of tubes or other implements, as needed. They also feature a special “top grip lip” that makes installation and removal easy and that extends past the sides of the opening for a more secure seal. Our thru hole barrel stoppers are manufactured from FDA grade/food grade silicone for safe and reliable sealing.

What is Silicone & Why is It Used for Bungs?
“Silicone” is the general name for a large family of polymers, including any synthetic compound consisting of repeating units of siloxane. Silicone’s most common form, silicone rubber, is utilized in a broad range of applications. This material is non-reactive, stable, resistant to fungal growth, and is well-suited to use in harsh environments and extreme temperatures (-75° to 450°F/-60° to 232°C). Silicone rubber maintains its dimensional tolerances at high temps and doesn’t become brittle in subzero conditions.
Thanks to its beneficial chemical and mechanical properties, and the ease with which it can be manufactured and molded, silicon rubber is an ideal material for whiskey barrel stoppers. Ace Seal uses special, FDA-approved food grade silicone for all our barrel bungs.
