ABSTRACT:
Fittings and methods for manufacturing fittings for piping are disclosed. The fittings are assembled from three identical molded pieces joined along longitudinal edges. Interfitting pieces form the joints between the sections and serve to draw the sections together during assembly and ensure roundness of the fitting. The technique is especially useful for the manufacture of fittings such as well screens, of synthetic polymeric materials.
