Loctite 598 is a high-performance, black RTV (Room Temperature Vulcanizing) silicone gasket maker designed for forming reliable, flexible seals on rigid flanged connections. This professional-grade sealant cures upon exposure to moisture in the air to create a tough, durable rubber gasket that resists oil, water, and automotive fluids.

Key Features:

• High-temperature resistance up to 650°F (343°C) intermittent exposure
• Excellent resistance to engine oils, transmission fluids, and coolants
• Sensor-safe formulation will not damage oxygen sensors
• Superior adhesion to aluminum, steel, cast iron, and composite surfaces
• Low odor, non-corrosive formula
• Remains flexible after curing to accommodate thermal expansion and vibration

Ideal for sealing oil pans, valve covers, timing covers, water pumps, thermostat housings, and other gasketed assemblies in automotive, marine, and powersports applications. The black color provides a professional appearance and makes it easy to verify complete coverage during application.
