Loctite 586 Thread Sealant 50ml

Loctite 586 Thread Sealant is a high strength, red anaerobic thread sealant engineered for maximum efficacy in locking and sealing copper and brass fittings. This industrial-grade adhesive permanently seals cylindrical metal assemblies, preventing costly fluid and gas leaks caused by vibration loosening and structural thermal expansion. Whether you are securing copper couplings or coarse metal hardware, this premium thread sealant provides a robust, leak-proof seal on all metal connections—including specialized brass and copper fittings.

Why Choose Loctite 586?

• Slow Cure Advantage: Provides an extended cure time particularly suited for fine adjustments or copper and brass fittings where traditional anaerobic sealants might react too quickly.
• High-Pressure Performance: Once fully cured, it forms an exceptionally resilient barrier that delivers a maximum-pressure seal to block severe fluid migration.
• No Creep, Shrink, or Shredding: The thixotropic dimethacrylate ester formula completely fills voids without shrinkage, ensuring no loose debris contaminates or clogs sensitive fluid systems.
• Positive UV Fluorescence: The formula glows bright under UV light, making quality control monitoring and application inspection incredibly easy.
• Exceptional Fluid Resistance: Maintains outstanding chemical tolerance against water, motor oils, unleaded gasoline, brake fluids, and industrial solvents.

Simple Application Instructions

1. Clean: For optimal results, clean all internal and external surfaces with a Loctite cleaning solvent and allow to dry completely to remove cutting oils or grease.
2. Apply: Apply a 360° bead of liquid thread sealant to the leading threads of the male fitting, leaving the first thread completely free.
3. Assemble: Assemble and wrench-tighten the parts securely. The formula will begin curing slowly once it is confined between the mating metal surfaces in the absence of air.

Frequently Asked Questions (FAQ)

What is Loctite 586 used for?

Loctite 586 is a high strength anaerobic thread sealant designed for the permanent locking and sealing of metal pipes, fittings, and cylindrical joints. It is specifically formulated to prevent assemblies from failing or leaking under heavy operational shock and high-vibration conditions.

Can Loctite 586 be disassembled?

No, not under normal circumstances with hand tools alone. Because Loctite 586 is a high-strength permanent thread sealant, you must apply localized heat to approximately 250°C (480°F) to degrade the cured polymer bond before dismantling the connection while hot.

Does Loctite 586 work on copper and brass?

Yes. Loctite 586 is highly effective on active metal connections and offers optimized performance across both brass and copper fittings. Its slow-curing trait ensures you have enough time to properly align and tighten these reactive metals before the bond locks into place.

Is Loctite 586 safe for standard industrial environments?

Loctite 586 is BAM approved for specialized applications. This means it is safe and approved for standard industrial, automotive, and plumbing trade assemblies up to a maximum service temperature of 150°C (300°F).
