Solid lubricant anti-seize paste for bolted metal joints
CO-GRAF LX 320 is a top-quality anti-seize compound composed of pure copper and
colloidal graphite in a high heat-resistant carrier. It is designed to lubricate and
protect threaded connections and flanges at temperatures to 1022°F (550°C) and
extreme load pressure conditions. CO-GRAF LX 320 has water-resistant and anti-oxidant
properties, does not separate, and is formulated to withstand lengthy service and severe
conditions. Stress, strain, and time to disassemble are greatly diminished.
