<p>The disclosure relates to a glow plug in which an outer metal housing (12) has a wall defining an internal axially extending bore (13), and a tubular heater having an external tubular sheath (16) has a heated end (16a) extending outwardly of the housing and an opposite internal end (16b) with the housing bore. An electrical heating element is positioned within the heater sheath and has a conductor (18) extending outwardly from the other end of the sheath. Electrical insulating materials fills the space between the heating element and the sheath (16), and an insulative compressible member (50) is compressed between the sheath (16) and the conductor (18) and the housing wall (12) with an interference fit to prevent the flow of gas into the interior of the tubular heater.</p> |
