Abstract
An electrical bushing is provided to facilitate the passage of electrical conductor leads from thermocouples or the like through a pressure barrier. The bushing includes a casing and a deformable, resilient, elastic plug which is disposed in a central conductor receiving bore of the casing in surrounding relationship to the conductors. Thus, when the plug is compressed in a direction axially of the casing, the plug tends to expand laterally radially and into sealing contact with the internal surfaces of the bore and with the electrical conductors.
