High pressure seal fitting with built-in low pressure seal arrangement

A high pressure seal fitting with a built-in low pressure seal arrangement for sealing a space defined by an inner diameter of a pipe and a rod slidably disposed within the pipe and extending beyond an end of the pipe, said fitting comprising:

• a fitting body provided with an axial passage for slidably accommodating the rod and having a first and region constructed for engaging the end of the pipe for forming a high pressure seal between the pipe and said fitting body, and a second end region opposite said first end region and including an outer circumferential protrusion having the shape of a ferrule for cooperating with components utilized to form a releasable high pressure compression seal;
• and
• low pressure seal means disposed in the axial passage at said second end region of said fitting body for maintaining a low pressure seal between said fitting body and the rod when said releasable high pressure seal is disconnected, said fitting body being disposed radially intermediate said releasable high pressure compression seal and said low pressure seal means.
