Patent ID: 7708923

Claim:
A process of molding a coupling for interconnecting a primary tube and a secondary tube, comprising the steps of: inserting a primary core pin into an end of the primary tube, inserting a secondary core pin into an end of the second tube to abut with the primary core pin at an intersection, wherein the first and second tubes are spaced apart from the intersection; inserting the primary and secondary tubes and the primary and secondary core pins into a mold cavity such that the intersection is exposed to the mold cavity; injecting a thermoplastic material into the mold cavity to form the coupling interconnecting the secondary and second tubes, wherein injecting the thermoplastic material is performed such that the thermoplastic material contacts the primary and secondary core pins at the intersection; removing the coupling and the tubes from the mold cavity; disengaging the secondary core pin from the primary core pin; removing the secondary core pin from the secondary tube; and removing the primary core pin from the primary tube.
