Silicone bungs

Silicone bungs which you will come across also under the name of silicone stoppers, are something that is very useful and everyone who has ever tried to seal a bottle or been anything else where there is some liquid, knows it. Both rubber and silicone bungs are the best available option when you need to prevent gas or liquid from escaping bottle or some other object.

So you can find them in a variety of places, from the lab to the winery. Both rubber and silicone have a lot of similar characteristics, but if the bung should be in contact with food, for example, then silicone is used. Also, silicone is even more elastic, which means that it will even better prevent gas and liquids from escaping because it will fit perfectly in any hole. Silicone bungs are still often used in biology, food science, home brewing as well as for medical purposes, primarily in hospitals. Silicone is FDA approved for food contact.

In addition to being very effective for this purpose, silicone is also very durable and practically does not age. It is non-toxic and no harmful chemicals are used in the production of silicone bungs. Silicone bungs can withstand a huge temperature range, up to almost minus 100 and over 250 degrees Celsius, so there is almost no environment where there are not suitable. You will find silicone bungs of various sizes, and it is important that you choose the right one or otherwise silicone bungs may not fully fulfill their purpose. This is equally important, whether you use silicone bungs to seal a wine barrel or a chemical bottle. To make sure they will be tight fit, compare the diameters of the opening and silicone bungs. Although they are usually white, you can choose the color you want, so red is often used for labs.
