Teflon gaskets are made out of a material called Teflon, which is extremely resistant to corrosion. The only drawback with using Teflon in any kind of high-volume manufacturing environment is that the material itself is soft and can easily be bent by intensive heat. Over the years, teflon gaskets have been used most often in industrial applications, such as soldering, pipe threading, soldering brazing, and metal coating parts with paint.
However, the use of Teflon gaskets for sealing purposes has also been found in other non-industrial applications, particularly in the refrigeration industry. In fact, many commercial refrigeration products have been manufactured with Teflon gaskets as the primary component in their seals. An example of this would be the ice cube tray in many restaurants, which is provided with a silicone seal to keep the cubes from sticking to the sides of the tray. If you look at a freezer next time when you’re searching for a new way to store your food, you may very well find that some commercial refrigerators contain these gaskets as a standard component.
The most common applications for Teflon gaskets are those related to electronics. While this may seem strange at first since it is unlikely that manufacturers would place such a hard-wearing, corrosion-resistant material into an area where high temperatures are routinely used, there are a number of reasons why this is the case. First, the material is generally quite inexpensive. It’s also not difficult to find suppliers and manufacturers that specialize in this material and who offer a variety of different styles. Finally, the material has a very long shelf life even in instances where it is exposed to extreme temperatures, which means that it can last a long time without having to be replaced. These factors make Teflon gasket materials a very good option for a wide variety of applications.
