K383 Copper Anti-Seize Grease

K383 Copper Anti-Seize Grease is a high quality lead-free anti-seize compound from Morris Lubricants, manufactured from high quality mineral oils, non-soap thickener, copper powder, and graphite. Designed to prevent seizure and galling in threaded and jointed components, K383 continues to perform even under extreme conditions — where excessive compression squeezes out most of the compound, or excessive temperature flashes off the oily component, a fine film of copper particles always remains in joints and threads to prevent seizure.

Suitable for use in saturated conditions including chemical environments and salt water, K383 is recommended wherever eventual disassembly must proceed smoothly. It assists sealing on pipe threads carrying very hot and corrosive liquids or gases, and enables fast and easy dismantling of components subjected to high temperatures — allowing them to be reused after dismantling. Apply sparingly by brush to both threaded surfaces prior to assembly for optimum performance.
