Permatex 51580 Anaerobic Flange Sealant 300ml Cartridge Purple

Permatex Anaerobic Flange Sealant is a professional-grade, single-component gasketing material designed for rigid machined metal flanges with gaps less than 0.015 inches. This medium-strength, thixotropic gel cures in the absence of air when confined between close-fitting metal surfaces, forming a tough, resilient seal that withstands extreme conditions.

Key Features:

• OEM-approved anaerobic formula cures rapidly in 1-12 hours without air exposure
• Temperature resistant from -65°F to +300°F (-54°C to 149°C)
• Eliminates the need for pre-cut paper, rubber, and cork gaskets
• Flexes with flange movement from vibration, pressurization, and thermal changes
• Purple gel formula with low VOC content (less than 2%)
• Solvent and temperature resistant once cured

Common Applications: Water pumps, thermostat housings, transmission pans and case covers, engine cases, timing covers, transaxle casings, axle covers, compressors, and O-ring replacement.

This 300ml cartridge is ideal for professional technicians and serious DIY enthusiasts who need a reliable alternative to traditional gaskets. The anaerobic technology ensures a secure, leak-free seal on rigid metal flanges.
