Loctite LOC37229 C5-A Copper Anti-seize Lubricant 20 Gm

Product Description

The LOCTITE LOC37229 is a copper-based anti-seize lubricant packaged in a 20 gram tube. Anti-seize compounds are applied to threaded fasteners, pipe fittings, studs, and bolts to prevent galling, seizing, and corrosion under high-heat and high-pressure conditions. The C5-A formulation uses copper particles suspended in a carrier grease to provide a reliable barrier between mating metal surfaces. This product is used by HVAC technicians, plumbers, pipefitters, and millwrights during installation and service of threaded connections that will be exposed to elevated temperatures or harsh environments.

C5-A copper anti-seize is commonly applied in residential and commercial HVAC systems on compressor bolts, flange studs, and exhaust or flue connections. Plumbers and pipefitters use it on threaded pipe joints and valve stems where corrosion or heat cycling could make future disassembly difficult. The 20 gram tube format is suited for field service work and small-volume jobs where a bulk container is not practical.

Key Features

• Copper-based formula provides high-temperature protection against galling and seizing
• 20 gram tube for portable, single-job or field-service use
• C5-A formulation suitable for threaded fasteners, studs, flanges, and pipe fittings
• Helps prevent corrosion between mating metal surfaces during long service intervals
• Eases future disassembly of connections exposed to heat cycling or corrosive environments

Compatibility

Designed for use on threaded metal fasteners, pipe fittings, flanges, and studs in HVAC, plumbing, and general mechanical applications where copper-based anti-seize is specified.

Installation Notes

Anti-seize lubricant is typically applied by HVAC technicians, plumbers, and pipefitters during assembly of threaded connections. Apply a thin, even coat to the male threads before assembly — excess material can contaminate sealing surfaces or interfere with torque readings, so use sparingly. Always follow applicable codes such as the IFGC or IPC for gas and plumbing connections, and verify that copper-based compounds are compatible with the specific metals and service fluids involved before application.
