Reliable sealing for threaded connections
- Immediate low-pressure joint sealing: You achieve an instant seal on metal pipes and fittings, preventing fluid leaks directly after completing the assembly.
- Loctite locks against vibration: By filling the space between threads, you protect the assembly from loosening caused by mechanical vibration or shock.
- High chemical fluid resistance: You benefit from excellent thermal stability, ensuring the compound will not shrink, creep, or tear under harsh operating conditions.
With Loctite 577 pipe sealant, you instantly create a reliable seal on metal pipes and threaded fittings to prevent fluid and gas leaks. Thanks to its thixotropic paste consistency, the sealant stays cleanly in place during application without running or dripping. By completely filling the space between threads, it locks assemblies securely against loosening from shock and mechanical vibration. The anaerobic formula delivers excellent thermal and chemical resistance on both active and passive metals, ensuring the seal will not shrink or tear under demanding conditions. With its medium-strength formulation, you can easily disassemble connections using standard hand tools for straightforward maintenance.
