Description
Product Overview
Realth Copper Anti‑Seize Lubricant is engineered for demanding applications where heat, moisture and metal‑to‑metal contact are constant challenges. Formulated with fine copper particles suspended in a high‑performance grease base, it offers superior thermal stability, corrosion resistance and electrical conductivity. Available in 30g and 60g copper‑colored tins, the compound meets automotive, marine and industrial specifications, providing a durable barrier that protects threads and surfaces from seizing, galling and rust.
Usage
Designed for brake system maintenance, spark plug installation, exhaust bolt tightening and marine hardware assembly, this lubricant excels in high‑heat zones and humid environments. Apply a thin layer to threads before assembly to ensure smooth tightening and future disassembly without damage. Ideal for mechanics, DIY enthusiasts and marine technicians who need a reliable, all‑purpose anti‑seize solution.

Why Choose Us
Realth combines decades of material science expertise with rigorous quality control to deliver a product that outperforms generic anti‑seize greases. Each batch is tested for temperature tolerance up to 600°F, corrosion resistance in salt spray, and electrical continuity. Our copper‑based formula provides a unique conductive path, preventing arcing in battery terminals and grounding connections—features rarely found in standard anti‑seize compounds.

FAQ
Can this lubricant be used on aluminum threads?
Yes, the copper particles are non‑abrasive and safe for aluminum, providing the same anti‑seize protection without causing galling.
What is the maximum operating temperature?
The formulation remains stable and effective up to approximately 600°F (315°C), making it suitable for brake caliper and exhaust bolt applications.
Does it affect electrical conductivity?
Unlike many anti‑seize greases, Realth’s copper‑based compound maintains a conductive path, preventing arcing in battery terminals and grounding connections.
How long does the protective barrier last?
When applied correctly, the barrier can protect threads for years, even in harsh marine or high‑humidity conditions.
Is it safe for use on fuel system components?
Yes, the grease is formulated to be compatible with fuel system materials and will not degrade seals or hoses when used as directed.
