Solid food grade pure tan gum stopper. Can be easily drilled to fit airlock, thermometer, etc.
Made of chemical tolerant pure tan gum

Although often referred to as a "rubber bung" or "rubber stopper," our bungs are made from food grade pure tan gum, NOT rubber. This is used specifically because it is highly chemical tolerant, specifically to ethanol whereas rubber is not.

Bottom- 1 3/4", Top- 2 5/64"
Fits our Pro Series II and Pot Distiller columns

    Tan gum rubber bung

    Purchased this to drill out for a thermometer on a 2" column. Overall satisfied with product. Only reason it is not 5 stars is that it was a little smaller than I'd like, and when inserting my thermometer it got pushed down into the column. Didn't cause any issues, still sealed great and the run went fine, but next time I'll get the mediums for this size application, even if it means having half of it sticking out the top.
