Abstract
A pressure vessel joint for repeaters in submarine optical communication systems is described. The joint employs a breech ring which secures an endcap to the pressure vessel. The breech ring and pressure vessel have corresponding keys. The breech ring slides over the endcap and is rotated such that the breech ring keys engage the mating keys formed in the pressure vessel. The endcap is seated on a preloaded C-ring which seals the secured structure. Additional, redundant piston seals can also be provided to further prevent leakage.
