Abstract: This disclosure relates to all plastic drain, waste and vent fittings whereas an annular formed in place over-mold seal is part of the fittings. This annular formed in place over-mold seal that has internal lips of multiple designs, provides a seal against the outer surface of the pipe being inserted and allows for slight misalignment, expansion and easy assembly. It is a one step bonding process of the same material that reduces both manufacturing assembly and material. This formed in place over-mold seal is of the same material as the fitting but has a softer composition.
