Hollow Wine Barrel Bung with Top Grip Lip


Click image to enlarge

Hollow wine barrel bungs are hollow in the center, making them lighter, more flexible, and easier to install in challenging applications. The special “top grip lip” makes installation and removal even easier and extends past the sides of the barrel opening for a more secure seal. Our hollow wine barrel stoppers are manufactured from FDA grade/food grade silicone for safe sealing with high reliability.

What is Silicone & Why is It Used for Bungs?

“Silicone” is the general name for a family of polymer materials; it includes any synthetic compound consisting of repeating units of siloxane. Silicone rubber is the most common form of silicone. Widely used in a broad range of applications, silicone rubber is non-reactive, stable, and resistant to fungal growth. It can be used in harsh environments and extreme temperatures (-75° to 450°F/-60° to 232°C) without losing its useful properties—silicone rubber doesn’t become brittle in subzero conditions, and maintains its dimensional tolerances at high temps.

Its chemical and mechanical properties, and the ease with which it can be manufactured and molded, make silicone rubber an ideal material for wine barrel bungs. Ace Seal uses special, FDA-approved, food grade silicone for all our barrel bungs.
