Product details
Description
Loctite 37616 Copper Anti-Seize Stick is a premium, high-viscosity, copper-based lubricant engineered to shield metal parts from extreme conditions. It provides a robust protective barrier for studs, bolts, flanges, and other mated components, preventing seizing, galling, and cold welding even when exposed to intense heat up to 1800 degrees Fahrenheit.
Ideal for automotive and mechanical applications, this high-temperature shield is widely trusted for exhaust manifolds, brake calipers, spark plugs, rod ends, and jam nuts. Designed with a convenient lipstick-style applicator, it ensures a clean, precise, and less messy application compared to traditional pastes.
The advanced gel formula stays in place without running, making it highly effective for overhead or vertical surfaces. Whether used on copper, brass, steel, stainless steel, cast iron, or non-metallic gasketing materials, this anti-seize compound ensures smooth disassembly and protects your valuable equipment from rust, corrosion, and stripped threads.
How to use
- Ensure the metal surfaces are clean, dry, and free from old grease or debris.
- Twist the base of the stick to expose the product.
- Apply a thin, even layer of the copper anti-seize compound directly onto the threads or mating surfaces of the hardware.
- Assemble the parts as normal and wipe away any excess lubricant.
- Read all safety cautions regarding skin and eye irritation on the back panel before use.

FAQs
What is copper anti seize?
Copper anti-seize is a high-temperature lubricant infused with copper flakes and other extreme-pressure additives. It is applied to metal fasteners, bolts, and spark plugs to prevent them from seizing, galling, or rusting together. This ensures that components can be easily disassembled in the future, even after exposure to intense heat.
Where to use copper anti seize?
It is ideally used on high-temperature and high-pressure mechanical areas such as exhaust manifold bolts, brake caliper slides, spark plug threads, oxygen sensors, and chassis hardware. It can be applied to various metals including steel, stainless steel, brass, copper, and cast iron.
Is copper anti seize better?
Copper anti-seize is superior for high-temperature applications up to 1800 degrees Fahrenheit and offers excellent electrical conductivity. However, for applications involving aluminum parts where galvanic corrosion is a concern, or stainless steel in highly corrosive environments, nickel or marine-grade anti-seize may be preferred.
Is this Loctite Copper Anti Seize Stick available in India an authentic import?
Yes, this product is a 100% authentic USA import. Dropy India sources these specialized maintenance products directly from authorized suppliers in the United States, ensuring that Indian mechanics, racers, and DIY enthusiasts receive genuine, professional-grade Loctite formulation.
What is the curing time for this anti-seize lubricant?
This anti-seize compound functions as a non-curing lubricant and paste to allow easy disassembly. While the formula settles efficiently upon application to prevent running, it remains active as a protective shield and does not dry out or harden completely like a threadlocker.
