Permatex 51531 Anaerobic Flange Sealant 50mL Tube

Permatex Anaerobic Flange Sealant is a professional-grade gasket maker designed to replace traditional pre-cut gaskets on rigid flanges. This fast-curing formula creates a superior seal that resists cracking, shrinking, and migration caused by thermal cycling and vibration.

Key Features:

• Anaerobic formula cures in the absence of air between metal flanges
• Creates flexible, reliable seals on rigid machined metal-to-metal surfaces
• Fills gaps up to 0.020 inches for optimal sealing performance
• Resists temperatures from -65°F to 300°F (-54°C to 149°C)
• Resistant to automotive fluids including oil, gasoline, transmission fluid, and coolant
• Allows for disassembly with standard hand tools when needed
• 50mL tube provides controlled application for precision work

Ideal for use on timing covers, differential covers, transmission pans, oil pans, valve covers, and other flanged assemblies. This sealant eliminates the need to stock multiple gaskets and ensures a reliable, leak-free seal on demanding automotive, marine, and industrial applications.
