Expanded PTFE (ePTFE) Gasket Sealing Tape
Adtex is a low cost alternative pure expanded PTFE sealing tape
It is equal in function to very expensive brands, but is less than half the price.
Adtex ePTFE is a cord or tape of pure PTFE extruded by a special process that expands and orientates the PTFE, making it soft and flexible. It is for use in flanged joints which are permanently bolted. Adtex ePTFE is supplied in flattened cord or thick tape form with a self-adhesive strip to allow easy installation on vertical surfaces.
ePTFE is a unique material offering special properties of importance to the process industries.
Advantages of Adtex ePTFE Sealing Tape
- Simple, trouble free fitting
- Universal application
- Minimum wastage
- Long life
- High degree of reliability
- Completely non-toxic and hygienic
- Low and simple stock holding
- Extremely cost effective
These properties are used to advantage in Adtex ePTFE gasket tape, where one product can be used to seal virtually all flange faces in process plants, in process conditions of up to 260 °C. It can therefore be used as a universal jointing, eliminating the need to stock different grades of gasket for different chemicals and process conditions, and as it is supplied in tape form, different gasket sizes no longer have to be stocked.
We're pleased to announce that we can now offer ePTFE tubing for any applications that require a very high permeability.

Being microporous, ePTFE is significantly different to conventional PTFE tubing – the material is air-permeable, soft & flexible, and feels somewhat like smooth, spongey marshmallow to the touch. It is also chemically resistant with high linear strength, chemically inert, remains watertight at low pressure, has a low dielectric constant, and offers excellent radial expansion and UV resistance too.
