Krytox™ TS4 PFPE sealant is a fully fluorinated grease designed for threaded connections on valves, actuators, pipe fittings, and fasteners.
Operating temperature range of –54–149 ºC (–65–300 ºF).
Primary Chemistry: PFPE
Features & Benefits
Unlike PTFE tape, which should be removed before re-application, Krytox™ TS4 can be re-applied over existing Krytox™ thread sealant. • Lubricates threads, preventing costly thread damage from galling and seizing during assembly. Allows low breakaway torque for easy-to-break connections. • Clings to threads and will not shred or tear on assembly/disassembly. • Cannot plug or restrict critical piping, valves, or instruments like tape solids. • Krytox™ TS4 is non-reactive, non-toxic, nonflammable, non-corrosive and compatible with most seal, O-ring, and valve polymers. • No VOC content or hydrocarbon in the product; safe for oxygen use with no auto-ignition temperatures. • Cost-effective—only a small amount of sealant needed per application. • Fast and easy to apply, even while wearing protective gloves. • Tested leak free under helium at 400 psi for 7 days.*
Clean all pipe and fitting threads with a non-chlorinated solvent to remove cutting/protective oil and chase threads with stiff wire brush to remove burrs, debris, and old sealant (PTFE tape, pipe dope, anaerobic resin, etc.). • Check pipe and fittings against ASNI/ASME guideline B.20.1-1983 to meet specifications for proper fit and engagement. • Construct piping systems following all applicable ANSI/ASME codes. • Apply Krytox™ TS4 to fill the male threads evenly, up to the recommended engagement length from the ANSI/ASME guideline. DO NOT OVERTIGHTEN.
Krytox™ TS4 allows for low breakaway torque for easy-to-break connections, preventing galling, seizure and thread damage. It is easy to apply via a specially designed applicator, reducing work time, injuries to fingers and damage to process equipment due to loose pieces of tape.
