Abstract

An adjustable joint having an outer housing section and an inner housing section telescopically disposed within the outer housing section. The inner housing section has an exterior portion within the outer housing section and which defines a circumferentially extending shoulder. An annular seal is positioned on the shoulder to create a seal between the outer housing section and the inner housing section. A circumferentially extending heat insulating spacer is attached to the shoulder and abuts the seal to retain the seal in place. A circumferentially extending heat shield is rigidly connected to the shoulder and abuts the heat insulating spacer and is located such that the heat insulating spacer is positioned between the heat shield and the annular seal. A circumferentially extending retainer ring is connected to the shoulder and abuts the heat shield to retain the heat shield, heat insulating spacer and annular seal in place so that when outer housing section and inner housing section move axially or rotate with respect to each other, the sealing function of the annular, metallic seal is maintained.
