LOCTITE® NS 5550 Extreme Temperature Sealant
Features and Benefits
A brown, thermally reactive fibrous paste sealing compound for high-temperature applications.
LOCTITE® NS 5550 is a brown, thermally reactive sealing compound, ideal for high-pressure and high-temperature applications up to 815°C (1500°F). When exposed to heat, it cures to form a seal. It will not permanently join the flanges together and will not interfere with future repairs of metal-to-metal joints.
- Heat-curing
- Temperature resistant up to 815°C (1500°F)
- Seals up to 345 bar (5,000 psi)
- Non-sag and chemical-resistant
