Loctite 2203451 263 Red Threadlocker High Strength Oil Tolerant 6ml

Loctite 263 is a high-strength, red threadlocker designed specifically for permanent locking and sealing of threaded fasteners in demanding automotive and industrial applications. This anaerobic adhesive cures in the absence of air between close-fitting metal surfaces, preventing loosening and leakage from shock and vibration.

Key Features:

• High-strength formula provides maximum locking power for permanent assemblies requiring disassembly with heat and hand tools
• Oil tolerant surface insensitive formula works on contaminated surfaces including as-received parts with minor oil residue
• High-temperature resistance up to 450°F (232°C) for use in engine compartments and exhaust systems
• Fluorescent red color allows for visual inspection under UV light to verify proper application
• Works on all metals including passive substrates such as stainless steel, aluminum, and plated surfaces
• Prevents rust and corrosion while locking threads
• Thixotropic gel consistency prevents migration after application

The 6ml tube size is ideal for maintenance, repair, and small assembly operations. Loctite 263 is particularly suited for automotive applications where oil contamination cannot be completely eliminated, making it perfect for engine work, transmission assemblies, and drivetrain components that require permanent fastener retention.
