Sealon PTFE Gasket Tape Demonstrated In Our New Video

Sealon PTFE Gasket Tape is an incredibly versatile product. Made from expanded PTFE (AKA Teflon), Sealon replaces conventional gaskets and can be applied directly to the flange face. It’s a simple, fast, and permanent alternative to using a cut-gasket and is versatile enough to cover many different sealing applications.

One of the things we’ve come across over the years though is the misconception that it would be hard to install. After all, a tape replacing a gasket; there has to be some trick to it right? Not really. You definitely need to ensure that Sealon is ok for your application (pressure, temperature, medium, compression all continue to play a part) but apart from that it’s really quite simple.


Rather than try to explain in words how easy it is to seal a flange with Sealon, we decided the best thing we could do is to show it. To do this, we’ve put together the video below.

Every roll of Sealon is produced for pure PTFE which allows it to offer exceptional chemical resistance. In fact, it’s resistant to most chemicals with the exceptions of elemental fluorine and molten alkali metals. It’s also DVGW rated for use in sealing gas and meets FDA requirements for food application. A variant (without the adhesive backing) is also available for oxygen sealing (BAM approved).

Sealon withstands anything between -232°C and +315°C and is soft enough to compress at minimal torque.
