    HT-1800 Pure Copper Anti-Seize Lubricant High Temp 1800°F for Spark Plugs, Exhaust Bolts & Manifolds and More Lead-Free, Zinc-Free, Graphite-Free, Made in USA, 8oz Brush-Top Can

    • PROUDLY MADE IN THE USA Manufactured by Balmar, an Oil Center Research company, ensuring trusted American quality and professional-grade performance.
    • PURE COPPER FORMULA MAXIMUM PROTECTION Higher copper content than conventional copper anti-seize compounds means a denser, tougher lubricating film that outlasts and outperforms under the most extreme heat, pressure, and torque. When the job demands the best, reach for HT-1800.
    • RATED TO 1800°F Handles turbo bolts, exhaust manifold bolts, header bolts, marine hardware, and high-heat engine hardware where lesser compounds burn off or break down.
    • STOPS SEIZING, GALLING & CORROSION Forms a tough copper barrier that prevents metal-to-metal contact, thread stripping, and corrosion seizure so fasteners and connections break free cleanly every time, even after years of extreme heat and pressure.
    • WORKS ON SPARK PLUGS, EXHAUST BOLTS & MANIFOLDS AND MORE Also ideal for header bolts, brake caliper pins, flanges, gaskets, marine hardware, farm equipment, heavy machinery, and virtually any threaded connection, bolt, nut, stud, or fastener exposed to extreme heat, pressure, or corrosion. If it runs hot and needs to come apart later this is the one.
    • LEAD-FREE, ZINC-FREE & GRAPHITE-FREE Safe on all metals including aluminum, stainless steel, cast iron, and titanium. Resists acids, caustics, solvents, oils, and salt water without corroding or damaging surfaces.

    Rated up to 1800°F, Copper Seal II holds up on exhaust, manifolds, brake components, and more

    Performance

    HT-1800 Pure Copper Anti-Seize is built for the jobs that demand more. Its higher copper content creates a denser, tougher lubricating film that stays stable in storage, won't run on hot surfaces, and holds strong under extreme heat and torque – yet breaks out cleanly every time.

    Polymer 400 provides a microscopic lubricating coating that eliminates metal-to-metal contact.

    Protection

    HT-1800 forms a tough copper barrier that prevents galling, seizing, corrosion, and metal-to-metal contact across any threaded connection or surface exposed to extreme heat and pressure. From daily drivers to diesel trucks, marine, farm, and heavy machinery – it protects what matters.
