Abstract: A device for gas-tight connection includes: a first connection point with a terminal surface; a second connection point with a stationary, predetermined reference surface of a pipe flange connection, which is arranged relative to the terminal surface by an offset angle which is compensated for by angular offset compensation means; and a flanged disc unit. The first connection point includes a central ball-and-socket joint arrangement as angular misalignment compensation means. The central ball-and-socket joint arrangement has a tube section with a convex distal end region configured to interact in an articulated manner with a concave annular region, corresponding thereto, of the flanged disc unit. A side surface region of the flanged disc unit includes at least one adjusting screw for adapting to the offset angle so as to adjust a local distance to a counter-disc fixedly fastened coaxially to a pipe section adjacent to the convex distal end region.
