Claim 0:
1. A method of making a flexible conduit having a loop portion comprising:
providing a double cross shaped section of tubing;
providing a first Y or TEE section of tubing and a second Y or TEE section of tubing;
securing one end of the first Y or TEE section to the double cross shaped section of tubing via a first overmolded connector;
securing one end of the second Y or TEE section to the double cross shaped section of tubing via a second overmolded connector;
securing a second end of the first Y or TEE section to the double cross shaped section of tubing via a third overmolded connector; and
securing a second end of the second Y or TEE section to the double cross shaped section of tubing via a fourth overmolded connector;
wherein, when connected, the double cross shaped section, the first Y or TEE section, and the second Y or TEE section are three separate flexible tubing pieces that are bonded together via the first, second, third, and fourth overmolded connectors with the intersection between the double cross shaped section and the first Y or TEE section and the second Y or TEE section being spaced apart to leave a flexible tubing portion adjacent the intersections to minimize hold up volumes within the flexible conduit along the intersections when closed by a plurality of valves positioned around the intersections.
