This patent describes a thermoplastic flange adapter for fusing to an end of a thermoplastic tube. The flange adapter has a first end and a second end and is characterized by an annular flange at the first end and a generally tubular portion attached normally to the annular flange. The tubular portion has an exterior surface defining a first generally cylindrical portion having a first end and a second end connected by its first end to the flange, a first outside diameter next to the flange and a second generally cylindrical portion having a first end and a second end connected by its first end to the second end of the first generally cylindrical portion. The second generally, cylindrical portion has a second outside diameter less than the first diameter and an annular shoulder separating the first diameter from the second diameter. The tubular portion further defines a third generally cylindrical portion having a first end and a second end and a third outside diameter smaller than the second outside diameter connected by its first end via a flared or tapered shape to the second end of the second generally cylindrical portion. The second outside diameter is between the first generally cylindrical portion having the first outsides diameter and the third generally cylindrical portion having the third outside diameter. The second end of the third generally cylindrical portion corresponds to the second end of the flange adapter to form a transition section for fusing the thermoplastic tube to the flange adapter.
