Hi-Temp Thread Sealant EACH - Permatex

Permatex Hi-Temp Thread Sealant is a professional-grade solution designed to create robust, leak-tight seals on critical metal threaded fittings. Engineered for the most demanding high-heat, high-pressure, and high-vibration automotive and industrial environments, this sealant ensures connections remain secure while preventing thread galling and corrosion, which simplifies future disassembly and maintenance for technicians.

Key Features

• High-Temperature Stability: Maintains sealing integrity on components exposed to elevated exhaust and engine temperatures, crucial for minimizing rework in demanding automotive and industrial settings.
• Versatile Fluid & Gas Sealing: Provides a durable seal against leaks in fuel, oil, coolant, steam, air, and various industrial process lines.
• Vibration Resistance: Helps maintain the tightness of threaded connections in engines, heavy equipment, and industrial machinery subjected to thermal cycling and mechanical shock.
• Corrosion and Seize Protection: Shields threads from rust and galling, enhancing serviceability when sensors, plugs, and fittings require removal.
• Chemical Durability: Formulated to withstand exposure to common automotive and industrial fluids, supporting extended service intervals and ensuring long-term reliability.

Applications

Permatex Hi-Temp Thread Sealant is suitable for a wide range of automotive and industrial applications, including:

• Threaded oxygen sensors, EGT sensors, and other exhaust fittings on gas and diesel vehicles.
• Engine and powertrain components such as temperature and pressure sensors, and coolant fittings.
• Hydraulic and pneumatic fittings found on shop equipment, construction machinery, and material handling systems.
• High-temperature threaded connections in boilers, HVAC systems, and hot water or steam lines.
• Industrial process piping, valves, and instrumentation where threaded joints encounter both heat and aggressive fluids.
