Loctite 234202 Anti-seize Lubricant 1 Lb Copper

Product Description

The LOCTITE 234202 is a copper-based anti-seize lubricant formulated for high-temperature and high-load threaded connections. Supplied in a 1 lb can, this compound protects fasteners and fittings from galling, corrosion, and seizure across an operating range of -29 degrees C to 1,800 degrees F. It is VOC compliant and rated for marine-grade applications. Mechanical contractors, plumbers, pipefitters, and industrial maintenance technicians apply it to bolts, studs, flanges, and fittings during assembly to ensure reliable future disassembly. The copper composition provides robust thermal stability in environments where standard lubricants would fail.

This anti-seize compound is suited for residential and commercial mechanical installations involving high heat or corrosive exposure. Typical applications include exhaust system hardware, boiler and heat exchanger fittings, flange bolts on steam lines, and threaded connections on pumps and valves. It is compatible with all alloys, brass, cast iron, copper, stainless steel, steel, plastic, and non-metallic gasketing materials, making it a versatile compound across multiple trade disciplines including HVAC, plumbing, and industrial maintenance.

Installation Notes

Apply by licensed or qualified mechanical tradespeople during assembly of threaded connections, flanges, or studs. Clean and degrease mating surfaces before applying the compound to ensure proper adhesion and effectiveness. Follow all local codes and manufacturer torque specifications for fastener tightening — this compound may affect friction coefficients and required torque values. Keep container sealed when not in use and store in a temperature-controlled environment.
