CRC Copper Anti-Seize and Lubricating Compound 75ml Tube

CRC Copper Anti-Seize and Lubricating Compound is a copper-based, general purpose anti-seize lubricant. CRC's data sheet says it prevents seizing and galling caused by high temperatures, heavy loads, vibration and corrosion, and gives an operating temperature range of -70°C to +982°C.

It comes in three formats: a 75ml tube, a 500ml brush-top pot and a 400ml aerosol with the Permastraw dual-action spray. CRC lists it for bolts, nuts, studs, fittings, flanges, manifolds and other threaded or closely fitted parts. The pastes and the aerosol are classified differently on the safety data sheets, so check the format you are buying.

Where this product is used

• Bolts, nuts, screws and studs
• Threaded surfaces, fittings, plugs and pipes
• Flanges, gaskets, headers and manifolds
• Bushings, packings and wire
• Closely fitted parts that need extreme lubrication (CRC wording)

Features

• Copper-based compound; CRC lists it for ferrous and non-ferrous metals
• Operating temperature range -70°C to +982°C (CRC data sheet)
• Electrically conductive: CRC says it does not insulate or interrupt current flow
• CRC says it does not compromise the integrity of soft metals
• Will not harden, so heat ageing does not affect lubricity (CRC data sheet)
• Facilitates fast and easy disassembly (CRC data sheet)
• 400ml aerosol includes the Permastraw dual-action spray system (CRC)

Key specifications

Available sizes

Selecting the right option

For stainless steel CRC positions CRC Nickel Anti-Seize & Lubricant Compound, and for incidental food contact it lists CRC Food Grade Anti-Seize and Lubricant 227g.

Using it

CRC's directions: read the entire label. Clean scale and old compound from threaded surfaces. Coat the mating surfaces and assemble. Do not use a thinner. Keep the container closed when not in use. Use a dust mask when grinding or wire brushing.

Aerosol (3195): do not apply while equipment is energised. Shake vigorously to free the agitator ball and mix the contents, and shake periodically during use.

CRC says the product contains hydrocarbons and must not be used in oxygen service.

Storage and handling

For the aerosol, CRC says not to puncture, incinerate or store above 49°C, and to use only in a well ventilated area. Keep containers closed when not in use.

Limits and safety

Hazards differ by format. Paste (3145 and 3183): the SDS (20/12/24, revision 1.2) does not classify it as hazardous under Safe Work Australia criteria and gives no signal word; it is not a dangerous good for transport, and is Class C2 combustible. Aerosol (3195): the SDS (03/04/25, revision 2.4) classifies it as an extremely flammable aerosol. Signal word Danger. H222: extremely flammable aerosol. H229: pressurised container, may burst if heated. UN 1950, aerosols, Class 2.1. CRC's data sheet says aerosol cans conduct electricity, so keep them away from live electrical sources. The product contains hydrocarbons and CRC says not to use it in oxygen service. Read the safety data sheet before use.
