Joint Sealants & Gasket Tapes » Gore Expanded PTFE Joint Sealant

GORE® Joint Sealant, the original form-in-place gasket, is the most cost-effective alternative to sheet gasketing for large equipment flanges. GORE® 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. GORE® 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.
