ABSTRACT:
The invention comprises a non-weld coupling and method adapted to connect two conduits. The conduits may be pipes, hoses, valves or the like and may be cylindrical, rectangular or the like, in shape. The first embodiment relates to conduits where there may be a degree of misalignment therebetween and which the coupling is adapted to accommodate. In this first embodiment, the coupling comprises a seal flange, seal block and seal ring. The flange, block and ring have mating surfaces defining a radius of curvature which permit the components to be pivoted and rotated relative to the pipe while still maintaining a fluid or air tight fit therebetween. The second embodiment relates to the coupling of two conduit segments in substantial alignment.
