20mm butyl stopper

Rubber stoppers have a unique design that ensures they perfectly fit a vial or a container and create a tight seal. This way, air, gases, and liquids cannot penetrate the vial, and its content is safe. Not only this, but a 20mm butyl stopper also ensures that the liquid stays inside the vial. Thus, it prevents spilling and any kind of contamination. When it comes to the design itself, these items have a cylindrical shape with a tapered bottom that goes inside the container. Due to the natural flexibility of rubber, installing these items is pretty easy, and their body guarantees perfect results every time. Due to this fact, it is not surprising that these stoppers have multiple uses.

Now, let’s talk about their size. Our merchandise comes in several dimensions, and a 20mm butyl stopper is only one type of product we offer. This range is necessary because, as previously mentioned, these have not only numerous purposes but also the size of vials and containers greatly differs. Therefore, we can offer you a perfect seal regardless of your requirements. If you have done any research on this merchandise, you have surely understood that these items are essential pieces in your toolbox if you enjoy working on DIY projects, which is why it is a good idea to purchase butyl stoppers in several sizes. 

Lastly, let’s discuss some vital properties of these items. As already stated, there is natural flexibility, but also rubber is resistant to chemicals, harsh weather conditions, sunlight, etc. When it comes to a 20mm butyl stopper, its flame resistance is not very good due to the fact that these products need to be kept at a temperature between -50 and 250°F. There is another thing you have to keep in mind. In ideal conditions, when maintained and stored properly, this product’s damping properties are very good, but it decays when exposed to temperatures above the mentioned range.
