13mm stopper
The 13mm stopper offered in our selection is manufactured from the highest quality of raw materials available on the market. This particular part is suitable for a wide range of application processes, mostly because it comes in various sizes, styles, and of course, rubber formulations, which is exactly what allows it to be used across different industries. Depending on the application, the 13mm stopper could, for example, be used for maximizing the sealing of different vials that have straight-wall glass finishes. This particular stopper type should not be used for vials that have a blow-back feature, mostly because they won’t be suitable for the application.
Since they can be easily snapped on a wide range of surfaces including glass, metal, wooden, and plastic surfaces, our clients won’t have to learn how to use our 13mm stopper, and more importantly, they will not require any additional tools and/or equipment that’ll help them install it properly. Additionally, since it features a ‘lock’, it’ll provide a tight seal, and the 13mm stopper won’t back out of the surface it was applied to, meaning that our clients won’t have to worry about it malfunctioning.
As we mentioned, it is manufactured from high-quality, durable materials, which is exactly what makes it resistant to various things. For starters, it could be utilized in both outdoor and indoor environments, it won’t be affected by aging, it’s resistant to most chemicals and some acids, and if you worry about dust, grime, humidity, and dirt, don’t, it’s resistant to those substances as well! Out 13mm stopper can also withstand extremely high and low temperatures, which is exactly what allows our customers to use them in various settings and work environments. It is also durable and strong, yet completely flexible, thus, if there is a need for using the 13mm stopper in extreme conditions, it will function without issues and hindrances.
