KRYTOX™ TS4 High Performance Thread Sealant

Krytox™ TS4 sealant is designed for diverse use on various metal and plastic surfaces. TS4 can be used in lieu of PTFE tape. In contrast to PTFE tape, which needs to be removed before reapplication, Krytox™ TS4 sealant can be reapplied over existing thread sealant; allowing for efficient and time-effective use.

KRYTOX™ TS4 High Performance Thread Sealant

Krytox™ Ts4 contains no volatile organic compound (VOC) content or hydrocarbon; making it safe for oxygen use with no auto-ignition temperature. Krytox provide high performance lubricants, sealants and greases for various uses and applications.

Krytox™ TS4 is effective for a number of reasons:

  • It clings to threads and will not shred or tear on assembly or disassembly; allowing for use in challenging environments and applications.
  • It cannot plug or restrict critical piping, valves, or instruments, which is often a problem with tape solids; again showing the diverse applications of the TS4 product
  • TS4 is cost-effective since only a small amount of sealant is needed per application. Overall, not only does it reduce costs through lower use of materials, but it also allows many teams to eliminate and replace outdated sealing methods.
  • Fast, safe, and easy to apply, even while wearing protective gloves; allowing a wide variety of personnel to be able to apply the product with minimal error and maximum efficiency.
  • Operating temperature range of -54 to 149 ºC (-65 to 300 ºF); making it highly diverse and applicable in various environments.
