Abstract
An access site for a fluid delivery system is disclosed. The apparatus comprises a rigid, tubular housing having a stepped inlet end, an outlet end and a bore therebetween, the stepped inlet end having an initial larger diameter cavity than the bore. Within the inlet end is a solid resilient sealing member having a larger and smaller cross dimensional portion positioned within the corresponding portions of the cavity and bore. The resilient member includes an axially parallel perforation and at least one axially protruding sealing ring on the large cross dimensioned portion of the sealing member in contact with a shoulder of the housing. Also included is a means for securing the member in the housing such that the resilient member experiences axial compressive forces at all points of axial contact between the member and housing.
