Fitting and method of manufacturing a fitting for attaching flexible tube to rigid tube

A method of forming a fitting for attaching flexible tube to rigid tube, the method comprising:

• overmolding a metal sleeve with a polymeric material, the metal sleeve having an axis of symmetry, the overmolding securing the polymeric material and the metal sleeve to each other, the polymeric material thereafter encircling the metal sleeve and the axis of symmetry and forming a female socket spaced from the metal sleeve that is configured and adapted to snugly receive an end of a rigid tube in a manner such that the female socket is in direct contact with the rigid tube, the polymeric material and the socket being configured and adapted to be solvent bondable to the rigid tube, the fitting having a fluid passageway that extends through the female socket and the metal sleeve, a portion of the polymeric material that encircles the metal sleeve forming at least one annular rib or barb and being configured and adapted to snugly slip into the end of a flexible tube with press fit.
