Abstract: A piping suspender with a metal-to-metal seal includes a piping hanger with an annular extension received in a counterbore of a well head and confined by a head adapter. The extension includes upwardly and downwardly facing, generally horizontally disposed shoulders. The upwardly facing shoulder abuts with the lower face of the head adapter and the downwardly facing shoulder abuts with an annular, generally horizontally disposed shoulder on the well head, to sealingly support the piping hanger and connected piping on the well head and to seal the hanger with respect to the adapter. A set of test lines are provided to enable seal testing.
