Drilled Rubber Stopper #10 Set of 3

These were a perfect fit for our fountain project. We needed to cut a slit in them to fit the plug for a pump. They were easy to cut and hammered in without any issues.

this project works as gem ❤️, staying on demijohn head tight, easy to apply, please don't forget to clean until demijohn head become completely dry to not slip off airlock. it is really handy tool in home brewing.

I was happy to get the stoppers because I had been sharting water chunks for a week and knew these would help stem the tide of the alcohol induced high pressure flow emanating from my bowels. When I finally figured out how to install them I was just about to explode again with a tirade of wretched nastiness the likes no one has ever seen. I shoved the stopper into place just before the rush of chunky style soup exploded out of my butt The first one didnt get installed correctly and shot across the room taking out a mirror, a vase, and giving my cat a concussions. The second, slit right into place and stopped the endless stream. What a great product.... 5 stars...Will drink again.

Great value for these rubber stoppers - perfect fit for plastic 5 gallon carboy (word to the wise - this size stopper will not fit in a 5 gallon glass carboy)

cheap and works. 5 stars if it were cheaper

We make wine in the 20 liter plastic jars that are used to deliver drinking water to offices and homes. The #10 stoppers fit perfectly, allowing us to fix airlocks during fermentation. The soft rubber stoppers that come with many airlocks are meant for smaller carboys. One word of warning.... Because this rubber is so hard, one has to be careful when putting the plastic airlock tube in. It doesn't give very easily.

Great for 5gal water cooler jugs. Be sure to dry( inside of jug too!) and hold in place to allow it to expand in jug neck. Put paper towels in microwave for a min if concerned about contaminating while drying it, or air dry

It's a stopper, it's rubber, and it's drilled. What more is there to say? It's tapered and round so you can stick it in stuff. There's a hole in the middle too, so in an ironic turn of events, you can stick stuff in it too. This drilled rubber stopper is not a super ball... If you throw it at the ground, it will bounce in random, sometimes dangerous directions. So don't do that.

They work great for my carboys. The Vapor valves fit fine in the hole.
