We call it a 'flyaway' fitting.  Simply 1/4" SS tubing held with an 
o-ring that forms a slip fit attachment: Cajon/Swagelok.  There 
is a check valve between the separation point and the tank.  It 
works quite well at 600 psi.  We replace the o-ring after each
flight.  We pressurize from 150' away.
