Readi-Seal™ PTFE Joint Sealant is soft & conformable, 100% virgin expanded PTFE, FDA compliant, easy installation &

Readi-Seal™ Expanded PTFE Joint Sealant is a soft, compressible gasketing material made of 100% pure, expanded PTFE. It is a form-in-place gasket that conforms to almost any sealing surface. Upon compression, it forms a thin, hard ribbon that fills in surface irregularities and creates an extremely tight seal. It is capable of withstanding a wider range of pressures, temperatures and chemical environments than any other soft gasket.

Readi-Seal™ can be used in just about any accessible bolted joint that features a flat or serrated sealing surface. It is also easy to install and remove, making it a highly versatile and cost-ffective solution for many demanding sealing applications.


  • Form-In-Place: conforms to any surface, including rough, pitted, scratched and damaged surfaces.
  • Flexible: can be installed on round, oval, rectangular and complex surfaces.
  • Chemically Resistant: made without fillers or binders, our 100% PTFE Joint Sealant exhibits the same chemical inertness of pure virgin PTFE.
  • Adhesive-Backed: convenient adhesive strip and peeloff backing allow easy installation on both horizontal and vertical surfaces.
  • Readi-Seal: has an Unlimited Shelf Life, shows No Age Deterioration, and Resists Creep & Cold Flow
