Material Notes:

Thermoseal® soft-chem® expanded PTFE sealing material provides excellent corrosion resistance and impermeability along with superior creep resistance and sealability for use in all types of applications. The material's high compressibility enables it to deform under load and conform to irregularities in flange faces for a tight seal with low, minimum sealing stress. Standardizing with it also helps to reduce maintenance, simplify inventory, and save money. Can be used with more fragile piping systemsIdeal for boiler applications because it's largely unaffected by steam or condensate for longer life and trouble-free sealingBAM approval for gaseous oxygenIndefinite self lifeFDA compliantInformation provided by Thermoseal Inc.
