Blue Monster Copper Guard is manufactured from a copper-filled PTFE resin. The PTFE provides excellent lubricity, while the copper flakes act as slide or bearing plates between the two mating threaded surfaces.

This construction helps reduce galling during both assembly and disassembly. When wrapped around a threaded component, the tape also helps shield the threads from dirt, grit, and corrosive substances that could contribute to seizure.

Copper Guard will not harden or crack on the joint and requires no curing time, allowing components to be assembled immediately after proper application.

Blue Monster Copper Guard is designed to permit easy assembly and disassembly of threaded components. It replaces messy anti-seize compounds with a clean tape format that can be applied directly to the male thread.

The PTFE provides lubrication while copper particles remain between the two mating surfaces, reducing friction and helping prevent galling.

This makes Copper Guard useful for threaded components that may require future inspection, maintenance, adjustment, or removal.

The PTFE portion of Copper Guard has a published temperature range of -450°F to +500°F (-268°C to +260°C).

PTFE remains stable up to approximately 500°F (260°C). If the PTFE portion decomposes at elevated temperatures, the remaining copper powder can continue providing anti-seize assistance. Copper flake has a melting point of approximately 1,984°F (1,084°C).

Always confirm the allowable temperature range of every component in the complete assembly. The lowest-rated component determines the allowable system temperature.

Copper Guard is wrapped around the male thread before the component is assembled. The PTFE conforms to the thread geometry and provides lubrication between the mating surfaces.

Copper particles dispersed throughout the tape act as microscopic slide or bearing plates, helping keep the mating surfaces separated and reducing the risk of galling or seizure.

The tape also creates a barrier around the threads that helps keep out dirt, grit, and corrosive substances.

• Confirm Copper Guard is suitable for the threaded component material and service.
• Do not use Copper Guard on stainless steel threaded components.
• Clean the male and female threads thoroughly before application.
• Wrap the tape around the male thread.
• Keep the tape under tension so it molds into the root of the thread.
• Wrap the tape in the same direction as the thread.
• Do not allow the tape to overlap the end of the fitting.
• Three wraps will seal most threaded connections according to manufacturer literature.
• For components up to 1-1/2" diameter, use 1/2" wide tape.
• For components above 1-1/2" diameter, use 3/4" wide tape.
• Keep the tape clean and replace the spool clip after use.
• Store the product in a clean location.
• Do not use on oxygen systems.

Copper Guard is compatible with a wide range of gases, liquids, and metal piping materials, but copper content makes material and chemical compatibility important.

The manufacturer states that acids can react with copper on the surface of the tape. For applications where copper cannot be tolerated, an alternative product should be selected.

Copper Guard is not recommended for stainless steel and must not be used to seal oxygen lines. For stainless steel, use Blue Monster Nickel Guard. For oxygen service, use an appropriate oxygen-rated sealing product.
