LOCTITE® 565 Thread Sealant 250ml

LOCTITE® 565 PST Thread Sealant 250ml is a low-strength white / off-white thread sealant engineered for maximum efficacy in locking and sealing metal threaded pipe fittings. This industrial-grade adhesive permanently seals and secures joints, preventing costly pressure leaks and fluid loss caused by shock, thermal cycling, or vibration. Whether you are securing hydraulic systems or compressed air lines, this premium methacrylate formula provides a robust, leak-proof seal on all metal threads—including stainless steel, brass, and aluminum.

Why Choose LOCTITE® 565?

• Anaerobic Cure: Cures efficiently in the absence of air when confined between close-fitting metal threads to create a durable, leak-proof seal.
• Universal Metal Compatibility: Provides exceptional performance across stainless steel, brass, aluminum, and other metal fittings.
• High Viscosity & Thixotropic Nature: Ensures excellent gap-filling and prevents product migration or dripping during and after application.
• Vibration & Leak Resistance: Locks fittings securely against loosening caused by severe industrial shock, thermal contraction, or heavy vibration.
• Low Strength for Easy Disassembly: Allows for convenient maintenance, component adjustments, or disassembly using standard hand tools without damaging threads.

Simple Application Instructions

1. Clean: For optimal results, clean all internal and external surfaces with a compatible cleaning solvent and let dry to remove residual oils or debris.
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 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 thread sealant designed for the locking and sealing of metal pipes and fittings. It is specifically formulated to prevent threaded joints from loosening and leaking due to shock, vibration, and operational pressure.

Can LOCTITE® 565 be disassembled?

Yes. LOCTITE® 565 is a low-strength formula designed specifically for easy servicing. The components can be easily disassembled at any time using standard hand tools without the risk of damaging delicate or expensive threaded components.

Does LOCTITE® 565 work on plastic pipes?

No. LOCTITE® 565 is an anaerobic sealant that requires the presence of metal ions and the absence of air to cure properly. It is highly effective on metal surfaces like stainless steel, aluminum, and brass, but is not recommended for plastic fittings.

Is LOCTITE® 565 safe for high-temperature environments?

LOCTITE® 565 is rated for a continuous operating temperature range of -65°F to 300°F (-54°C to 149°C). For optimal shelf life and performance prior to application, the product container should be stored in a dry location between 8°C and 21°C.
