Royco 44 Anti-Seize, MIL-T-5544B

Royco 44 has a consistency similar to modeling clay and is black in color.

Royco 44 is recommended for use as anti-seize compound for threaded fasteners and fittings as well as spark plugs, igniters and similar threaded aircraft engine accessory equipment. Due to its graphite compound, this material should not be used in contact with aluminum, magnesium, cadmium or zinc alloys and platings without prior evaluation. Because Royco 44 conducts electricity readily, the mating of dissimilar alloys, which may create an electrical potential, should be avoided.
