BTAS Copper Antiseize Grease 8 oz Jar — High-Temp Copper-Flake Thread Protectant for Spark Plugs, Bolts & Electrical Contacts

BTAS Copper Antiseize Grease is a semi-synthetic, copper-flake lubricant that prevents seizing and corrosion on threaded metal parts while maintaining electrical conductivity.

Designed for automotive and industrial maintenance, this 8 oz jar of BTAS Copper Antiseize provides a durable, high-temperature barrier between metal surfaces to ease disassembly and reduce galling. Its formulation blends micro copper flakes, rust inhibitors, and a heat-resistant carrier to perform across a wide temperature span, so it’s suitable for underhood fasteners, exhaust components, and electrical connections that require both conductivity and corrosion protection.

How does BTAS Copper Antiseize protect threads during high-heat exposure?

Its micro copper content and heat-stable base resist breakdown at elevated temperatures, producing a thin, persistent film that prevents metal-to-metal bonding. The product remains effective where conventional greases would burn off, keeping threads serviceable after repeated thermal cycles.

• Effective temperature range from -30°F to 1800°F for long-term protection.
• Copper flakes reduce galling and promote electrical continuity on sensor and terminal threads.
• Forms a thin film so fasteners torque predictably without excess buildup.

Which parts and situations benefit most from this antiseize grease?

BTAS Copper Antiseize is formulated for areas where corrosion, heat, and electrical contact intersect. Typical uses include spark and glow plug threads, exhaust manifold bolts, oxygen sensor threads, wheel hub nuts, and battery cable connections—anywhere you need reliable disassembly and conductivity.

• Spark plugs, glow plugs, and sensor threads to prevent seizure and ensure removal.
• Exhaust and engine bolts exposed to thermal cycling and corrosive gases.
• Battery terminals and knock sensor connections where conductivity matters.

How do I apply BTAS Copper Antiseize for best results?

Surface prep and a conservative application are key: clean away loose dirt, oil, and rust, then spread a thin, even layer over the threaded area or mating surface. Wipe off excess—only a light film is necessary to maintain protection and avoid contamination of surrounding parts.

• Clean surfaces before application to remove contaminants and old lubricants.
• Apply a thin coat along thread crests or the contact surface for predictable torque.
• Wipe away extra product; thin coverage maximizes performance and prevents drip.

Will this product affect torque specs or sensor readings?

Because BTAS Copper Antiseize leaves a controlled, thin film, it minimizes torque variation compared with heavy greases. Its conductive copper particles are compatible with threads that require electrical continuity, but always follow manufacturers’ torque recommendations where specified.

• Thin film helps maintain consistent torque without extensive overshoot.
• Copper flakes preserve electrical pathways on sensor and terminal threads.
• Check OEM guidance for torque values on critical fasteners after antiseize use.

Who is this for: BTAS Copper Antiseize Grease is suited for professional mechanics, DIY automotive enthusiasts, fleet maintenance teams, and industrial technicians who need a dependable anti-seize that handles high temperatures and maintains electrical conductivity. Use it when you want easier future disassembly, protection from rust and corrosion, and a reliable conductive coating for threaded electrical components.
