Loctite® 586 is a red, high-strength, slow-curing anaerobic thread sealant designed for locking and sealing metal pipes and fittings. It cures in the absence of air between close-fitting metal surfaces, forming a durable seal that prevents loosening and leakage due to shock and vibration. The adhesive is particularly effective on copper and brass fittings, where traditional anaerobic sealants may cure prematurely.

Loctite® 586 is a single-component, anaerobic sealant formulated for sealing threads in metal pipes and fittings. Its slow-curing properties are especially suited for copper and brass substrates, preventing premature curing during assembly. The product cures at room temperature when confined in the absence of air between close-fitting metal surfaces, forming a flexible, chemical-resistant seal. Loctite® 586 is particularly effective on less active substrates such as stainless steel and plated surfaces and can cure through light coatings of industrial oils and cutting fluids without the need for prior cleaning. The adhesive exhibits temperature resistance up to 150°C, ensuring long-term reliability in demanding environments.
