Armite’s LP-250 High Temp Anti-Seize (2.7 oz) Commercial Grade LP-250 is a sealing compound that prevents seizing or galling at temperatures ranging from -350°F to 2987°F (-212°C to 1641°C). This compound consists of pure lead powder suspended in a non-volatile hydrocarbon vehicle and does not dry out, even when exposed to the atmosphere. Because lead is one of the least reactive of the metallic elements, the compound is highly non-contaminative and is impervious to the effects of salt, water, steam, oils, ammonia and hydrocarbons. LP-250 is only prohibited from use with pure oxygen and Freon gases.
