Loctite LB 8008 Copper Based Anti Seize Lubricant

LOCTITE® LB 8008 C5-A™ is used across automotive, industrial, and marine maintenance to prevent threaded fasteners and mated metal parts from seizing, galling, and rusting at temperatures up to +982°C (1,800°F). Its copper and graphite solids keep parts from welding together even after the base grease burns off under extreme heat.

Common Automotive & Fleet Uses

• Exhaust Systems. Coating exhaust manifold bolts, studs, catalytic converter fasteners, and turbocharger hardware so they can be removed without snapping.
• Brake Components. Lubricating brake caliper guide pins (metal-to-metal contact areas only), caliper bracket bolts, and the back of brake pads to prevent squealing.
• Engine & Ignition Hardware. Protecting spark plug threads in aluminum or cast-iron cylinder heads and preventing seizure on oxygen sensor threads.
• Wheel & Chassis Fasteners. Applying lightly to wheel hub faces (to prevent alloy wheels from corroding onto steel hubs) and suspension bolts.

Industrial & Plant Maintenance Uses

• High-Heat Equipment. Protecting bolts, studs, and hinges on boilers, industrial furnaces, heat exchangers, and foundry machinery.
• Pipe Flanges & Gaskets. Coating pipe threads, valve stems, flange bolts, and non-metallic gaskets in refineries, chemical plants, and power stations.
• Heavy Machinery & Steel Mills. Preventing wear and seizure on slow-moving linkages, press-fit shafts, bushings, and assembly pins.

Compatible & Restricted Materials

• Safe to Use On. Steel, cast iron, stainless steel, copper, brass, alloys, plastics, and non-metallic gasketing materials.
• Where NOT to Use. Do not apply to high-speed ball or roller bearings, rubber brake boots/seals (petroleum base can swell certain rubbers), or systems carrying pure oxygen or chlorine.
