Royco 44 is a heavy-duty anti-seize compound developed formulated to delicately blance electrical conductivity needs with corrosion resistant metal/metal allow contact suitability. Meets SAE-AMS-2518, formerly MIL-T-5544B. Shelf life 1095 days.

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 the graphite compound in Royco 44, 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.
