A pipe adapter includes a first tubular element, a second tubular element, and an annular securing member disposed around and fixed to a second portion of the first tubular element. The annular securing member has a flange portion that contacts and secures the second tubular element axially relative to the first tubular element while also allowing the second tubular element to rotate relative to the first tubular element and the annular securing member. An annular sealing member is located around the first portion of the second tubular element to provide an axial seal along the adapter.

A flexible pipe connector, including a tubular housing, a sleeve arranged within the tubular housing, the sleeve including a first end having a first spherical inner surface, the first spherical inner surface having a first inner radius, and a second end having a second spherical inner surface, the second spherical inner surface having a second inner radius, a first tubular member including a first spherical end and a first cylindrical end, the first spherical end having a first outer radius, smaller than the first inner radius, the first spherical end pivotably arranged in the first end, and a second tubular member including a second spherical end and a second cylindrical end, the second spherical end having a second outer radius, smaller than the second inner radius, the second spherical end pivotably arranged in the second end.

A disposable dental valve device is disclosed having a valve body having an interior, a tip receiving end for receiving a tip, a socket hose receiving end for receiving a tube having a beaded end, a lumen formed between the tip receiving end and the socket hose receiving end, and a partial opening formed in the valve body, a rotatable valve sealing body adapted to be inserted into the partial opening, and the rotatable valve sealing body having a bore for alignment with the lumen formed between the tip receiving end and the socket hose receiving end.

A push joint adapter is connectable to one or more push joint pipe fittings in a pipeline. The push joint adapter includes an insertion section insertable into a socket of a push joint pipe fitting in an interference fit, a pipeline section connectable with the pipeline, and a collar disposed between the insertion section and the pipeline section. A restraint ring assembly cooperable with the push joint pipe fitting includes a restraint ring secured to the pipeline section and engaging the collar and a restraint rod connected to the restraint ring. The push joint adapter facilitates connecting push joint gasketed bell gate valves and fittings in a pipeline such as a polyethylene pipeline.
