ABSTRACT:
A pipe coupling formed by a tubular plastic member having at one end a portion of increased diameter defining an inwardly facing annular recess, and an annular sealing ring bonded therein by a foot portion substantially filling the recess and having a sealing head portion projecting partway across the interior of the coupling and secured to such foot portion by a neck portion. The seal ring configuration lends itself to injection molding of the assembly.
