Expanded PTFE Joint Sealant
Kan-Seal Fluid Sealing Products - Expanded PTFE Expanded PTFE Joint Sealant, the original form-in-place gasket, is the most cost-effective alternative to sheet gasketing for large equipment flanges. Joint Sealant can be used in practically every type of sealing application, and it is ideal for sealing complex surfaces and rough or pitted flanges. Joint Sealant minimizes leak potential, lost production, maintenance time, and risk of catastrophic failure. It is the most reliable means of optimizing long-term system performance.
