Permatex High Temperature Threadlocker 6ml

Ensure the ultimate reliability and safety of your marine vessel with the PERMATEX High Temperature Threadlocker in a convenient 6ml tube. In the demanding marine environment, constant vibration, temperature fluctuations, and exposure to corrosive elements can compromise the integrity of critical threaded fasteners, leading to potential leaks, mechanical failures, and costly repairs. This professional-grade threadlocker is engineered specifically to combat these challenges, providing a permanent, high-strength bond and seal on your boat´s most vital components.

Designed for heavy-duty applications, this is the ideal solution for securing fasteners in high-stress areas. Whether you are performing routine maintenance on your engine, upgrading hardware, or undertaking a complete overhaul, this threadlocker provides the peace of mind that your assemblies will remain tight and secure, season after season. Its superior formulation is OEM specified, meaning it is trusted by professionals and manufacturers for locking and sealing fasteners from 3/8 inch to 1 inch (10mm to 25mm) in size.

High temperature.



Locks and seals threaded fittings.



Resists leakage vibrations loosening moisture hydraulic fluids and diesel fuels.



Won´t shred or wear like thread sealant tape.



The exceptional performance of this threadlocker makes it indispensable for any boat owner´s maintenance kit. Its ability to withstand extreme temperatures up to 450°F (232°C) makes it perfect for use on and around engine components, such as water pump bolts, thermostat housing, manifold studs, and engine mounting bolts. Unlike standard threadlockers, it will not fail or degrade when exposed to the intense heat generated within an engine compartment. This robust protection extends to chemical resistance, creating an impenetrable seal that stands up to saltwater, oil, and other common marine fluids, preventing corrosion and ensuring easy disassembly with heat when required.

Move beyond outdated and unreliable methods. While thread sealant tape can be messy, tear, and potentially contaminate sensitive systems like fuel or hydraulic lines, PERMATEX High Temperature Threadlocker offers a clean, liquid application that cures into a solid, thermoset plastic. This solid bond fills the gaps between threads, creating a unitized assembly that is impervious to vibrational loosening—the number one cause of fastener failure on the water. Trust PERMATEX to protect your investment, enhance performance, and keep you safely on the water
