ABSTRACT:
A P-trap device for plumbing drainage systems is shown. The device has a first tubing element having a pipe attachment bell at one end and a first coupler portion at the other end and a second tubing element having a pipe attachment bell at one end and a second coupler portion at the other end, wherein said first and second coupler portions are sized and shaped to be coupled together. The device further has at least one of said first or second tubing element being a generally unshaped section sized and shaped to trap water therein. A connector to releasably couple said first and second coupler portions together is included, the connector including a sealing gasket. The sealing gasket, first coupling portion and second coupling portion are sized and shaped to permit the first and second coupler portions to be coupled together over a range of angles to form a leak resistant joint without introducing stresses into the plumbing system. Most preferably the shape of the connecting portions is in the form of male and female matching part spherical sealing surfaces.
