ABSTRACT:
A separable electrical isolator for coupling two pieces of conductive tubing carrying high pressure cryogenic gas includes a gas-impervious dielectric spacer with a pair of opposing surfaces and a bore extending therebetween in which the pieces of tubing are sealed axially-aligned in fluid communication with an electrically-nonconductive gap between them. A pair of complementary coupling members are rigidly attached to the pieces of tubing to define outwardly-extending annular surfaces that are each sealed about the periphery of a corresponding piece in a position slightly set back from and facing an end of the piece. The coupling members are separably and nonconductively interconnected with the annular surfaces facing the spacer surfaces and O-ring seals in between to apply compressive force to the spacer and seals and thereby effect the seal.
