Fitting for medical piping system

A fitting for use with metal, corrugated tubing having peaks and valleys encased in a jacket, the fitting comprising:

• a nut including a first cavity and a second cavity and a shoulder extending radially inwardly between the first cavity and the second cavity, configured to receive the tubing through the second cavity;
• a sealing member configured for placement in a valley of the tubing, the sealing member including a sealing surface and a circumferential notch, the notch configured to abut against and receive the shoulder to limit movement of the sealing member;
• an adaptor including an adaptor sealing surface, the adaptor including a sealing ridge formed thereon, the sealing ridge having an outer diameter greater than an inner diameter of the first cavity, the adaptor being press fit into the nut by engagement between the sealing ridge and the inner diameter of the first cavity;
• a jacket lock ring configured for placement in the second cavity, the jacket lock ring including an outer surface including a tapered ramp and an inner surface including at least one ridge configured to engage the jacket;
• a swage sleeve configured for placement in the second cavity, the swage sleeve including a tapered surface facing the ramp on the jacket lock ring;
• wherein upon assembly, the adaptor is press fit into the first cavity and the swage sleeve is press fit into the second cavity, the tubing being compressed between the adaptor sealing surface and the sealing surface and the tapered surface of the swage sleeve engages the ramp of the jacket lock ring to drive the jacket lock ring towards the jacket.
