Loctite 302677 Anti-seize Lubricant 8 Oz Brush Top

Product Description

The LOCTITE 302677 is a high temperature anti-seize lubricant formulated with a graphite composition to prevent galling, seizing, and corrosion on threaded and mating metal surfaces. Rated for service up to 2000 degrees F, it is packaged in a convenient 8 oz brush-top container for direct, controlled application. The off-white compound is water-resistant and VOC compliant at 4.7 g/L. It is applied by HVAC technicians, plumbers, pipefitters, and industrial maintenance professionals on fasteners, flanges, and fittings exposed to extreme heat and harsh environments.

This anti-seize compound is suited for residential and commercial applications where high-heat threaded connections require protection against seizure and corrosion. Typical use cases include exhaust system fasteners, boiler fittings, furnace components, and piping flanges operating near or at elevated temperatures. It is compatible with a broad range of base metals, making it a versatile shop and field compound for trade professionals working across multiple system types.
