Abstract : Hypothetical approaches were evaluated first as ideas, then as models on special apparatuses, and finally as dry diving suits underwater. Parameters such as incipient leakage vacuum levels and seal 'stretch' were developed to compare the new ideas and conventional designs. A materials evaluation was also conducted for the applications and the new designs were built with optimal materials. A standard hooded Viking suit equipped with Viking face seal, riveted tooth gas sealing zipper extending fom the right side of head to right knee, and labyrinth type multiple lip neoprene wrist seals was the best effort suit delivered to the U.S. Navy.
