rubber stopper hole

Plastic stoppers generally serve to securely close glass bottles or other dishes in which certain contents would be safely stored. They are made in different shapes and sizes. They can be with or without threads and with or without holes in the top. Plugs with one hole or a few of them are used quite often, although the first association with a plastic plug in the flat one, without a hole. Hole plugs have a slightly more specific purpose and are not used too much in the household as is the case with flat plugs. Rubber stopper holes are most often produced in a conical shape. In this way, their universality is enabled, or better said, this cap can close any bottle or container that has differences in the width of the opening in a few millimeters.

Rubber stopper holes are carefully built and designed to make an air chamber and thus ensure a secure seal. In this way, fermentation and quality gas exchange are provided. You can be sure that nothing can get to the stored content even though there is a millimeter hole on it. However, on the other hand, this opening allows you to take a part of the stored liquid with a syringe or a certain hose without having to open the bottle completely. In this way, oxidation and loss of quality substances from the content itself are prevented. Also, if you need to constantly measure the temperature of the contents of the bottle, these plugs allow you to smoothly push the tip of the thermometer through the cap. As the rubber from which the plug is made is quite flexible, it is possible to expand and contract it, all as needed. With this cap, you can be sure that you have a great product because it is resistant to chemicals and their vapors, different oils, but also large temperature differences.
