Description
LOCTITE 515 Gasketing Sealant (Part No. 135479) is a high-performance anaerobic-curing flange sealant formulated to seal close-fitting joints between rigid metal surfaces. The product cures when confined in the absence of air, creating a durable, flexible seal that adapts to minor flange movements without loss of integrity.
LOCTITE 515 provides immediate resistance to low pressures after flange assembly, helping to reduce downtime during installation and maintenance. It is commonly used as a form-in-place gasket for applications such as pumps, compressors, thermostats, transmission housings, and axle covers.
For quality assurance and maintenance convenience, LOCTITE 515 is fluorescent under UV light, allowing easy visual inspection of the applied bead. This makes it a dependable choice for industrial maintenance, repair, and OEM assembly operations where precision sealing and reliability are critical.
