This roll of Sealon PTFE Tape is 5mm Wide x 20 Metres Long. Before it is compressed, it's about 2mm thick. Information on flange size suitability is included on the specifications tab and our Sealon e-PTFE Tape TDS which can be found on the media tab.

Sealon Adhesive PTFE Gasket Tape is a versatile, easy to use sealing tape that lets you make your own gaskets in an instant. It’s made from expanded PTFE which makes it very easy to shape and allows it to compress with only light bolt loads.

Sealon is an alternative to many cut-to-size gaskets. It’s supplied on a roll with a peel-off adhesive backing on one side to make placing it on the flange face easy. This also allows Sealon to be easily installed on vertical flanges and those with irregular faces.

Since it is made from pure, expanded PTFE; Sealon has a range of excellent sealing characteristics. These include outstanding resistance to temperature (-232°C to +315°C), excellent chemical resistance and very good sealing performance at low bolt loads.

Sealon Adhesive PTFE Gasket Tape is available in a variety of different size rolls to suit different sizes of flange. Once you’ve selected the size you need, installation is simple. Just position Sealon around the flange and overlap the two ends outwards past a bolt hole.

More information on installation as well as data on the technical characteristics of this instant gasket tape can be found on our Sealon Technical Data Sheet over on the media tab.
