Abstract

A connector body with a first end and a first part thereon and a second end and a first part thereon includes a passageway aligned along an axis passing through the first end and part. Openings in second part permit communication from the first end to the second end since the openings extend from the second end to at least the passageway. A male luer taper located on the first part about the passageway tapers outwardly of the axis from the first end to a annular groove. A luer nut with an internally threaded collar and an apertured flanged portion seats within the groove permitting rotary but not axial movement of the luer nut relative to the taper. A method provides a plurality of connections between openings and a passageway with a connector body having a first end and a first part thereon and a second end and a second part thereon and a passageway through the first part from the first end extends to a plurality of openings in the second part permitting communication. The method includes locating a male luer taper on the body. A groove near the taper may be included for an internally threaded luer nut.
