Expanded Joint Sealant

Readi-Seal™Expanded PTFE Joint Sealant
The Universal Gasketing Material ... On A Spool !


Readi-Seal™ Expanded PTFE Joint Sealant is a soft, compressible gasket material made of 100% virgin expanded PTFE. It is a versatile “form-in-place” material that will conform to almost any sealing surface. When compressed, it forms a hard, thin ribbon that fills-in surface irregularities, while creating an extremely tight seal. It has the capacity to withstand a wider variety of chemical environments, temperatures and pressures than any other soft gasketing material.

Readi-Seal™ Expanded PTFE Joint Sealant  can be easily used just about every accessible joint that features a flat or serrated sealing surface where the joining of the surfaces is accomplished through bolt force. With ease of installation and removal without scraping or grinding, it is a highly versatile and cost-effective solution to a wide variety of demanding sealing applications.


  • Form-in-Place - conforms to any surface, including rough, pitted, scratched and damaged. Excellent on warped flange surfaces.
  • Flexible - can be installed on round, oval, rectangular and complex surfaces.
  • Chemically Resistant – made without fillers or binders,  100% pure virgin Expanded PTFE Readi-Seal™ exhibits superior chemical inertness.
  • Adhesive-Backed – the convenient adhesive strip and peel-off backing allow for easy installation on both horizontal and vertical surfaces.

Readi-Seal™ Expanded PTFE Joint Sealant has an Unlimited Shelf Life, shows No Age Deterioration, and Resists Creep & Cold Flow.
