Silicone rubber stopper with hole

Silicone rubber stopper with hole has a very wide application, primarily for the fermentation process in wineries and as part of laboratory glassware. Silicone rubber stopper with hole can have one or two holes. Three-hole rubber stoppers are very rare. Silicone rubber stopper with hole, as well as rubber stopper without hole, has a primary role to prevent liquids from leaking, to prevent evaporation of gases and to prevent contamination of samples. While it may seem to you that the hole will hinder the silicone stopper from doing its job, it will not. Holes or more also have a role to play and that is why this type of rubber stopper is also available.

The shape of the rubber stopper is mostly similar because the shape is adapted to the neck of the bottle and other similar things like test tubes, so the shape is such that the rubber stopper can easily fit. So you need to measure the diameter, length and thickness. What makes silicone rubber stopper with hole different is that you also need to measure the diameter of the hole. The diameter of the hole on the rubber stopper depends on what you need the hole for. Will a measuring instrument or something else pass through it? You can find a large number of sizes with us, and if the size you need is not available, don’t worry, we can make any size you want.

We use silicone because silicone has many characteristics suitable for making a rubber stopper. For high temperature application, silicone stoppers are best. Silicone can withstand minus 80 to plus 250 degrees, and can be briefly exposed to minus 115 to plus 300 degrees Celsius. Also, silicone is odorless and tasteless, completely safe for contact with food, which is very important for wineries, for example.
