The Herschell Copper Anti-Seize 100g Tube is the bench-top version of the popular anti-seize lubricant. While the aerosol version is better for broad coverage, this concentrated paste in a squeeze tube is the professional's choice for precision application. It allows you to apply a thick, controlled bead directly onto threads, ensuring maximum protection against "cold welding" and high-temperature seizure.
Technical Specifications
- Base: Non-melt grease carrier with micro-fine copper flakes.
- Solid Lubricant: Pure Metallic Copper.
- Temperature Range: Effective from -30°C to +1100°C.
- Consistency: Thick, brushable/spreadable paste.
- Volume: 100g Squeeze Tube.
Key Features
- Precision Control: The tube format prevents "overspray" on brake discs or sensitive components. You can apply exactly what is needed to the bolt flutes without wasting product.
- High Copper Loading: Contains a higher concentration of solids compared to the aerosol version, providing a denser protective barrier for heavy-duty industrial fasteners.
- Vibration Resistance: Helps dampen vibrations in threaded assemblies, reducing the likelihood of fasteners "walking" or loosening over time while still ensuring they remain easy to remove.
- Sealing Properties: The thick paste helps seal out moisture and corrosive salts, acting as a gasket-like barrier for threaded pipe fittings and flange bolts.
Common Applications
- Brake Servicing: Applied to the back of brake pads (to stop squeal) and on caliper mounting bolts. Note: Keep away from the actual friction surface of the pad and disc.
- Exhaust Systems: Manifold studs, turbocharger bolts, and oxygen sensor threads (apply sparingly to threads only).
- Spark Plugs: Prevents steel spark plug threads from seizing into aluminum cylinder heads (common in modern engines).
- General Workshop: Pivot pins, sliding hinges, and any metal-to-metal contact point subjected to high heat or outdoor exposure.
Usage Tips
- Clean the Threads: Use a wire brush to remove old rust or grit. If the threads are dirty, the anti-seize will just lubricate the "sand," which can still cause the bolt to seize.
- The "Roots" Rule: Ensure the paste fills the roots (the bottom valleys) of the threads. A light smear on the tips is often not enough to prevent galling under high torque.
- Torque Adjustment: Because copper anti-seize reduces friction, you must reduce your torque setting by 10% to 20% compared to a "dry" bolt specification to prevent over-tightening.
- Galvanic Warning: Avoid using copper-based products on aluminum parts in saltwater/marine environments. In those specific cases, the copper can react with the aluminum; use Herschell Nickel or Ceramic Anti-Seize instead.
