High-strength and leak-free joint sealing with Loctite 586

Practical benefits

Ideal for brass and copper: The slow-curing formula prevents premature hardening on reactive metals, giving you ample time to align and torque your fittings.
High-pressure and vibration resistance: It polymerizes between metal surfaces to form a solid seal that withstands heavy vibrations, water, and industrial oils.
Clean application without clogging: The liquid completely fills thread roots without shredding or tearing, protecting pipework from loose debris and blockages.

In a nutshell

The right choise for

With Loctite 586 thread sealant, you achieve permanent, leak-free locking across rigid metal pipe joints and threaded fittings. This liquid sealant is specially formulated for reactive metals like brass and copper, featuring a slow cure time that gives you ample room to precisely align your components. Once anaerobically cured between tight metal surfaces, it creates a robust plastic seal that withstands high pressure, severe vibrations, water, and industrial oils. Because the liquid completely fills the thread profile without shredding or tearing, it keeps your piping systems entirely free from loose debris and blockages.
