PTFE thread seal tape is unsintered tape produced by rolling PTFE cord. Fluoroplastic-4D, which is used for this type of tape, is resistant to all acids, solvents, oils, and alkalis (except for alkali metals). Fluoroplastic-4D is a strong material; it has a wide range of operating temperatures and is resistant to water vapour as well as climatic and bacterial exposure. It also has excellent electrical insulation, anti-friction and anti-adhesive properties. Due to these qualities PTFE thread seal tape can guarantee leak tightness in threaded connections subjected to a pressure of up to 9.8 MPa. PTFE thread seal tape is self-lubricating, non-toxic, chemically inert, oil-resistant and corrosion-resistant.

Here are some of the qualities of our PTFE thread seal tape:

  • it is easy and convenient in use;

  • it has high thermal and chemical resistance;

  • it has excellent sealing properties;

  • it has an unlimited shelf life;

  • it is a certified product (hygiene certificate № 006997 of 09.10.1996)

PTFE thread seal tape is meant for sealing threaded connections of industrial pipelines that transport corrosive liquids and gases. It can also be applied to seal threaded connections in equipment used in the food, pharmaceutical, chemical, construction and other industries on condition that the pressure is lower than 9.8 MPa.

Operating temperatures range from 60 °C to + 200 °C.

We produce PTFE thread seal tape of the following measurements:

thickness – 0.10 mm to 0.14 mm;

width – 10.0 mm to 160.0 mm.
