Loctite 555352 515 Gasket Maker Flange Sealant Anaerobic 50ml

Loctite 515 Gasket Maker is a medium-strength anaerobic flange sealant designed for sealing rigid metal flanges and fittings in automotive and industrial applications. This purple-colored, single-component sealant cures in the absence of air between close-fitting metal surfaces to form a durable, solvent-resistant gasket that eliminates the need for pre-cut gaskets.

Key Features:

• Anaerobic formula cures between metal flanges without air exposure
• High temperature resistance up to 400°F (204°C) continuous
• Medium strength allows for disassembly with standard hand tools
• Fills gaps up to 0.010 inch (0.25mm) and compensates for flange irregularities
• Resistant to oils, fuels, coolants, and automotive fluids
• Eliminates corrosion and shrinkage associated with traditional gaskets
• Purple color for easy identification and inspection
• Convenient 50ml (1.69 oz) bottle size

Ideal for sealing engine oil pans, transmission housings, differential covers, thermostat housings, valve covers, and other rigid flange assemblies. Compatible with all metals including aluminum, steel, and cast iron. Provides reliable sealing performance in demanding automotive and powersports applications.
