Claim:
1. A pressure vessel apparatus for cryogenic capable storage of hydrogen or other cryogenic gases at high pressure and for connection to external components, comprising: a pressure container having a central axis; an interior cavity in said pressure container; an internally threaded opening in said pressure container, said internally threaded opening interfacing with said inner cavity; a two-piece insert adapted to be threadedly secured in said internally threaded opening in said pressure container; said two-piece insert including a first piece outer cylinder with a first piece outer cylinder parallel inlet duct in said first piece outer cylinder of said insert that is parallel with said central axis; a first piece outer cylinder perpendicular inlet duct in said first piece outer cylinder of said insert connected to said first piece outer cylinder parallel inlet duct in said first piece outer cylinder of said insert, wherein said first piece outer cylinder perpendicular inlet duct is perpendicular to said central axis and wherein said first piece outer cylinder perpendicular inlet duct and said first piece outer cylinder parallel inlet duct are connected; a first piece outer cylinder parallel outlet duct in said first piece outer cylinder of said insert that is parallel with said central axis; and a first piece outer cylinder perpendicular outlet duct connected to said first piece outer cylinder parallel outlet duct in said first piece outer cylinder of said insert, wherein said first piece outer cylinder perpendicular outlet duct is perpendicular to said central axis and wherein said first piece outer cylinder perpendicular outlet duct and said first piece outer cylinder parallel inlet duct are connected; said insert including a second piece inner cylinder with a second piece inner cylinder parallel inlet duct in said second piece inner cylinder of said insert that is parallel with said central axis, wherein said second piece inner cylinder parallel inlet duct is connected to said first piece outer cylinder parallel inlet duct; a second piece inner cylinder parallel outlet duct in said second piece inner cylinder of said insert that is parallel with said central axis, wherein said second piece inner cylinder parallel outlet duct is connected to said first piece outer cylinder parallel outlet duct; and a joint that attaches said first piece outer cylinder to said second piece inner cylinder.
