Ortman Key is a coupling device used to secure two adjacent cylindrical segments of a pressure vessel common in tactical rocket motors. An Ortman Key is made of elongated rectangular metal bar stock, such as steel, and is inserted into juxtaposed anular grooves around the circumference of the mating parts. The Ortman Key assembly is used in high pressure applications where packaging, strength and mass are important.
