7mm butyl stopper

You may not know this, but rubber stoppers are an essential item used in the manufacturing process of a wide variety of products. First of all, several pieces of equipment and furnaces used have holes that need to be sealed tightly to ensure their best performance. At the same time, there are products that need to be sealed, and this is especially important when it comes to containers and vials that hold liquid. Rubber stoppers not only ensure there is no spillage, meaning that the content remains safely inside the vial, but it also prevents contamination with other substances.

Since these holes can be of different sizes, a 7mm butyl stopper is the smallest item you will find in our offer. Naturally, we also offer stoppers in various sizes, which is why you should explore our merchandise if this one doesn’t meet your requirements. 

What are the main properties of a 7mm butyl stopper? Obviously, there is its size, meaning that it can perfectly fit and seal the smallest holes. Next, one of the essential features of rubber is its elasticity, making these products very easy to handle and install. Another property of butyl is its durability. This type of rubber is very resistant to all sorts of physical damage, abrasions, wear and tear, cracks, and the like. The bottom line is that it is very difficult to destroy a butyl stopper, which means that it will last you for quite some time as long as you use it properly. Not only this, but a 7mm butyl stopper can withstand effects from external factors, such as sunlight, harsh weather conditions, ozone, steam, and so on. When it comes to proper maintenance, the only thing you have to be careful about is the temperature of the room where these items are stored and installed.
