A tubular metal sleeve having two annular welding end collars and a flexible intermediate sleeve portion between the collars is mounted in a bore of a housing. The sleeve permits passage of high temperature pressurized fluids impervious to the sleeve. The sleeve forms part of a gauge for detecting the pressure of the fluid. A spacer may be mounted in a space formed between the sleeve and the housing to reduce the quantity of pressure-transmitting liquid required to fill the space.
