Fermentation TPE Rubber Stoppers – Drilled Bungs for Airlocks (#8 Drilled Stopper, 4-Pack)

Have bought these twice. Good quality, have zero complaints about these. Had to do measurements to make sure I bought the right size. Airlock fits tight and secure tightly in the carboy. Have noticed if the inside rim or the rubber is wet they tend to slip out of the carboy. Can be solved with making sure those are dry or taking a rubber band and wrapping around the finger loop and over top of the stopper. They are a little pricey in my opinion but should last a lifetime.

Needed to vacuum down a commercial truck hydraulic clutch cylinder and reservoir system,,,,, the dimensions were detailed and accurate (to fit the reservoir opening ),,,,the material was high quality,,,,, next day delivery ,,,,,,,, CAN YOU BELIEVE IT ! Shopping the Amazon is shopping the universe

I needed to center a shaft inside a tube in order to pour a polymer sleve on it. These were easy to drill to the right size and worked perfectly.
