Loctite 565 Thread Sealant

Loctite 565 Thread Sealant (50ml) is a low-strength, white to off-white anaerobic thread sealant engineered for maximum efficacy in the locking and sealing of metal pipes and fittings. This industrial-grade adhesive permanently fills the space between threaded metal parts, preventing costly fluid leaks and gas escape caused by operational shock and vibration. Whether you are securing industrial fluid processing lines or general commercial plumbing connections, this premium thread sealant provides a robust, leak-proof seal on all tapered metal pipe threads and fittings.

Why Choose Loctite 565?

• Instant Safeguard: Provides an immediate, high-viscosity low-pressure seal for air pressure testing straight after assembly.
• Controlled Lubricity: Formulated with controlled torque traits to prevent thread galling during assembly and protect joints from rust and corrosion.
• Fluid Resiliency: Offers excellent resistance to a wide variety of industrial fluids, including gasoline, petroleum oils, and natural gas.
• Thixotropic Formula: High-viscosity paste composition minimizes the migration of the liquid product after application, keeping it localized within the threads.
• Low Disassembly Force: Secures assemblies reliably against heavy vibration while remaining low-strength enough for quick, stress-free removal with standard hand tools.

Simple Application Instructions

1. Clean: For optimal results, clean all internal and external surfaces with a Loctite cleaning solvent to remove grease, oil, and old debris, then let dry.
2. Apply: Apply a 360° bead of the liquid thread sealant paste to the leading threads of the male fitting, leaving the first thread completely free.
3. Assemble: Assemble and tighten the parts as required. The formula will begin curing once it is confined in the absence of air between the close-fitting metal surfaces.

Frequently Asked Questions (FAQ)

What is Loctite 565 used for?

Loctite 565 is a low-strength, high-viscosity thread sealant designed for the locking and sealing of tapered metal pipes and fittings. It is specifically formulated to prevent threaded fasteners and connections from loosening or leaking due to continuous operational shock and fluid system vibration.

Can Loctite 565 be disassembled?

Yes. Loctite 565 is engineered with a low disassembly strength and controlled torque profile. This means it can easily be disassembled and broken down when necessary using standard manual hand tools without risking damage to the pipe fittings.

Does Loctite 565 work on plastic pipe threads?

No. Loctite 565 is an anaerobic adhesive that requires contact with active metal ions and the exclusion of air to cure properly. It is highly effective on metal pipe surfaces, but is not recommended for use on plastic or thermoplastic fittings as it will not cure correctly and could cause stress cracking.

Is Loctite 565 safe for drinking water lines?

Yes. Loctite 565 is certified to NSF/ANSI Standard 61. This ensures it is approved for safe use in commercial and residential potable drinking water systems (not exceeding 82°C), as well as systems handling natural gas, propane, butane, and petroleum oils within standard pressure limitations.
