1. A sealing connector comprising:
- a first component comprising;
a distal extension having a generally cylindrical shape and a distal bore providing a cylindrical cavity at a distal end of the distal extension;
a proximal cylindrical body coupled to the distal extension, the proximal cylindrical body having an outer diameter at least larger than an outer diameter of the distal extension;
a central bore having an open proximal end and an open distal end, the central bore traversing the proximal cylindrical body and the distal extension of the first component;
a tubing section disposed within the central bore; and
a transition fitting disposed within a portion of the central bore in the distal extension of the first component, the transition fitting abutting the tubing section; and
a second component comprising;
a generally cylindrical body having a central bore defined therein, the central bore providing a cavity that accommodates the distal extension of the first component when the first component is connected to the second component;
a coupling platform disposed within the central bore of the generally cylindrical body of the second component, the coupling platform having a generally cylindrical shape and being sized to fit within the open distal end of the central bore of the first component; and
a sealing member connected to the second component and disposed within a circumferential channel between the coupling platform and an inner surface of the central bore of the generally cylindrical body of the second component such that the sealing member engages the coupling platform and the inner surface of the central bore of the generally cylindrical body,wherein the transition fitting is interposed between the tubing section and the coupling platform and is in abutting connection with both the tubing section and the coupling platform when the first component is connected to the second component, andwherein the sealing member is configured for minimizing a gap between the first component and the second component to prevent fluid from being trapped therebetween.
