Profile: SeaCon/Brantner & Assocs., Inc. specializes in offering underwater electrical and fiber optic connectors. Our electrical dry-mate connectors are mated in air with the mating interfaces being kept dry and sealed from the external environment. Once properly mated, the connector can be submerged to it's rated depth. The 55 series of dry-mate connectors are available in 4 shell sizes and are manufactured from 316L stainless steel as standard, although other materials such as titanium,, aluminum, bronze and alloy 625 are also available as options. We manufacture a wide range of penetrators for use in applications in which a waterproof seal needs to be made between a cable and a pressure vessel. This is often accomplished using a connector set, but if there is no requirement to separate the cable from the equipment a penetrator, can be used.
