Which materials are suitable for Loctite 586?

It is engineered for metal pipe threads and fittings, working especially well on brass and copper.

How does this thread sealant cure?

It cures anaerobically at room temperature when confined in the absence of air between close-fitting metal surfaces.

What media does the cured sealant resist?

Once fully cured, it forms a high-pressure seal against water, oil, and most common organic liquids.

Can a joint sealed with Loctite 586 be disassembled?

As this is a high-strength sealant, disassemble using standard hand tools or apply heat up to 250 °C for larger joints.

Can Loctite 586 be used on plastic pipe threads?

No, this anaerobic thread sealant requires metal contact to cure and is not recommended for plastic substrates.

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.
