Abstract
A pressure guage connection for connecting a pressure sensing device such as a manometer or an electrical pressure detector to a pressurized vessel or conduit is disclosed. The connection element constitutes a cylindrical stem designed in one piece with the device carrier, with said cylindrical stem having a ring-type flange at its end. The ring-type flange places an attachment element to the cylindrical stem in an undetachable manner. The attachment element also has a deformation portion which is deformable in the radial direction after the placement onto the cylindrical stem, with a shoulder being formed as a result of the deformation and with the attachment element resting against the ring-type flange via this shoulder. The attachment element can be a clamping nut or a cap screw. A reinforcement seal is designed to be located at the end of the ring-type flange facing the pressurized vessel, with said reinforcement seal having a semi-circular, a semi-elliptical or a concavely bent cross section with a plane parallel, pressure-bearing surface area.
