7mm butyl rubber stopper
7mm butyl rubber stopper may seem like a very small Butyl rubber stopper and therefore not widely used, but is actually used in a variety of places, in many where you would never have guessed you could find a small diameter butyl rubber stopper. 7mm butyl rubber stopper is absolutely necessary in laboratories, because glassware from very small to very large diameter is used in laboratories. And what is necessary is to be the right size, because if it is loose, then the rubber stopper cannot fulfill its primary function, which is to prevent chemicals, gases and similar things from evaporating, because some are very toxic and that can be dangerous. And also to prevent oxygen and other substances from entering and mixing with chemicals and gases, because then the properties completely change and this would significantly change the results obtained by laboratory tests.
But labs are certainly not the only ones that will benefit from using a 7mm butyl rubber stopper. Various other industries, such as the chemical industry, as well as the military industry, the space industry and the music industry will use different forms of rubber stoppers. Wherever there is a small hole to be left with a very resistant rubber stopper, then a 7mm butyl rubber stopper is a great choice. Butyl rubber is a synthetic type of rubber whose durability is one of its main characteristics. Rubber stoppers made from Butyl are resistant to heat, weather, acids, various types of gases, as well as physical damage caused by the functions of certain machines where a rubber stopper can be implemented.
In case you need a rubber stopper made of a material other than Butyl, you can order custom ones from us. Also different sizes are available, not just 7mm. We also offer different colors so you can more easily recognize if you have multiple rubber stoppers.
