Replace PTFE Tape with Krytox™ TS4

Krytox™ TS4 Thread Sealant

Traditionally, PTFE tape is used to seal threaded piping on valves, actuators, and miscellaneous pipe fittings and fasteners - but it has some drawbacks.

Krytox™ TS4 PFPE sealant is a paste developed with superior sealing characteristics compared to a standard thread seal tape. Krytox™ TS4 PFPE sealant can be used with a wide variety of process fluids including water, air, steam, hydrocarbons, acids, bases, chlorines, and most reactive gases and liquids.  The TS4 thread sealant is also safe for oxygen use and critical piping application.
Krytox™ TS4 allows low breakaway torque for easy-to-break thread connections, preventing galling, seizure and thread damage. Krytox™ TS4 is easy to apply via a specially designed applicator, reducing work time, finger injuries, and process equipment damage due to loose pieces of PTFE tape. Krytox™ TS4 is also approved for re-application without needing to clean up the old sealant.


Benefits of Krytox™ TS4 Thread Sealant:

  • Perfect for threaded connections for valves, actuators, pipe fittings, and fasteners 
  • Safe — Chemically inert, nonflammable grease that won't react with metals, seal materials, or the process environment
  • Insoluble in nearly all gases and solvents; Krytox™ TS4 won't be stripped away during processing
  • Adheres to threads and will not shred or tear on assembly or dis-assembly like PTFE tape 
  • No VOC content or hydrocarbons
  • Operating temperature range of -54°C to 149 °C (-65°F to 300 °F)
  • Approved for use by The Chlorine Institute (Pamphlet 164)
  • Easy application and long-term seal performance
  • Tested leak free under helium at 400 psi for 7 days
