Rubber bung stopper

The main purpose of a rubber bung stopper is to plug tubes, flasks, bottles, and basically any type of container. Naturally, these items are made of rubber, which is obvious, and due to the material properties, they are used in several industries. When it comes to the design, a rubber bung stopper has trapped edges, meaning that top is wider than the bottom. This feature enables you to easily insert it into a bottle and plug it from the outside without distributing its content or decreasing the volume.

Now, when choosing these, the size is the most important thing you have to consider before putting in your order. Why? Well, the rubber bung stopper must fit the hole perfectly to seal the container completely and protect its content. Even though rubber is a flexible material, the chances are that you won’t be able to use the stopper that is too big. On the other hand, the smaller one won’t work either. You may be able to fit it somehow, but even if you manage to do this, you should think of it as a temporary solution until you have a chance to purchase the one you actually need. Since it is vital to use one of the appropriate dimensions, we offer a whole range of different rubber bung stoppers to our customers. 

In addition, you also have to investigate the material itself. Naturally, to make the best choice, you have to consider where you will store the containers, as well as the content they hold. For example, if the bottle holds harsh chemicals, you should go with FKM and Neoprene items that are resistant to high temperatures and strong acids. On the other note, if the stopper will be in direct contact with food, you should choose silicone ones that are safe and eco-friendly.
