Loctite 569 Thread Sealant 50ml

Loctite 569 Thread Sealant is a low strength brown hydraulic thread sealant engineered for maximum efficacy in thread sealing. This industrial-grade adhesive permanently locks and seals metal pipes and fittings, preventing costly fluid and gas leaks caused by shock and vibration. Whether you are securing hydraulic fittings or pneumatic connections, this premium thread sealant provides a robust, leak-proof seal on all metal threads—including close-fitting active and passive metal surfaces.

Why Choose Loctite 569?

• Prevents Loosening and Leakage: Cures when confined in the absence of air between close-fitting metal surfaces to stop vibrational loosening and fluid migration.
• Excellent Fluid Compatibility: Highly resistant to industrial solvents, hydraulic fluids, motor oils, and gasoline.
• Low Viscosity Formula: The 400 mPa·s liquid consistency easily wicks into fine threads and tight metal connections to completely fill voids.
• Ideal for Hydraulic & Pneumatic Systems: Specifically designed for fine filtration systems, servo mechanisms, and small-diameter metal pipes.
• Certified Gas Resistance: Approved by the Australian Gas Association (Certificate 3375 Class III) for reliable performance in demanding gas piping networks.

Technical Specifications

• Product Type: Anaerobic Methacrylate Ester Thread Sealant
• Strength: Low
• Color: Brown
• Container Size: 50ml
• Certifications: Australian Gas Association (AGA) Certificate No. 3375 Class III

Simple Application Instructions

1. Clean: For optimal results, clean all internal and external surfaces with a Loctite cleaning solvent and let dry.
2. Apply: Apply several drops of the liquid thread sealant to the leading threads of the male fitting, leaving the first thread free.
3. Assemble: Assemble and tighten the parts as required. The formula will begin curing once confined between the mating metal surfaces in the absence of air.

Frequently Asked Questions (FAQ)

What is Loctite 569 used for?

Loctite 569 is a low strength anaerobic thread sealant designed for the locking and sealing of metal pipes and fittings. It is specifically formulated to prevent hydraulic and pneumatic fittings from leaking or loosening due to continuous shock and vibration.

Can Loctite 569 be disassembled?

Yes. As a low strength thread sealant, components sealed with Loctite 569 can be disassembled using standard hand tools. For larger pipe diameters, applying localized heat can help break the bond more easily.

Does Loctite 569 work on stainless steel?

Yes. Loctite 569 offers robust performance across standard metal threads and fittings. It cures reliably when confined between close-fitting active metal connections as well as passive metal substrates.

Is Loctite 569 safe for gas line environments?

Loctite 569 is certified by the Australian Gas Association (Certificate number 3375 Class III). This means it is approved for use in gas piping and fittings up to a rated working pressure of 2000 KPa and a temperature range of -10°C to +150°C.
