BTS Copper Anti-Seize Lubricant combines a high concentration of copper enhanced with a blend of premium grade aluminum-complex grease and graphite to lubricate and insulate dissimilar metals from self-generated galvanic corrosion. BTS B-00011 prevents seizing and galling at high temperatures and pressures while permitting the easy removal of parts that have been subjected to adverse conditions. The spray pattern is smooth and precise and it comes with an extension tube for hard to reach areas. Also helps to lubricate and ensure proper torque during assembly. It won’t run or splatter whether it’s used with or without the extension tube.
