A connector and tubing assembly including a multi-lumen molded connector having at least three flexible tubes also molded into the connector. The connector may be “Y” shaped and include three flexible tubes. A process of making the connector and tubing assembly involves forming a first part of the connector with two tubes molded therein and then removing an internal mold member prior to molding the final connector portion and third tube in place.

A silicone tubing assembly comprising:
- at least three thermoset, silicone, flexible tubes each including a free end with an interior surface;
- and
- a silicone connector formed around at least a portion of all of the free ends to form a smooth, fluid-tight passage between the three tubes, such that a portion of the material of each of the three tubes forms a portion of the passage within the connector.
A mold and tubing assembly comprising:
- at least three silicone, hollow, flexible tubes each including a free end;
- first and second mold portions engaged to form a substantially closed cavity and supporting at least a portion of the three free ends within the mold;
- a passage forming assembly including a rod portion disposed within the free ends of each of the three tubes;
- and
- curable liquid silicone disposed in the cavity about the portions of the three ends and at least a portion of the passage forming assembly, wherein the passage forming assembly is configured to form a generally smooth passage between the three tubes after the liquid silicone is cured and the rod portion is removed.
