These gaskets are stamped out from a pure PTFE sheet. As they are susceptible to cold-flow they should generally be used on grooved flangs

The shortcoming PTFE is its susceptiblelity to cold-flow(creep). In this type of gasket, the cold-flow property has been improved with the admixture of an organic filter and the use of a special manufacturing technique. These gaskets combine an excellent heat- and chemical-resistance with a high cold-flow resistance and are ideal for use in pipelines handling all types of chemical products(such as highly concentrated hot sulfuric and nitric acids). They cannot be used for sodium hydroxide and other highly concentrated alkalis and hydrofluoric acid.

These wrapped gaskets use a NON-AS joint sheet instead of the conventional asbestos joint sheet as the center core.
Accordingto the structure of the center core, these gasket are classified into an N and S type. The N type gaskets are designed for general application. In contrast, the S type gaskets have a more sophisticated core structure to suppress the flow characteristics that are the particular feature of PTFE jackets. They are therefore suited for high-temperature and high-pressure application. VALFLON jacket Gaskets are available with three different jacket shapes.
