Flanged Fitting For Use With Tubing Containment System

A fitting coupled to metal tubing in a jacket, the fitting comprising:

• an adapter, the adapter having a tubular member defining a longitudinal passage having a longitudinal axis for fluid flow;
• a body for receiving the tubing, the body positioned opposite the adapter and aligned with the longitudinal axis, a vent opening formed through an exterior wall of the body;
• a sealing member positioned between the adapter and the body,
• a retainer positioned external to the sealing member, the retainer receiving the adapter and receiving the body;
• a first flange located near the adapter and a second flange located near the body;
• a ferrule at a second body end, the ferrule for engaging the jacket of the tubing to mechanically attach the fitting to the jacket, the ferrule providing fluid-tight seal between the ferrule and the body;
• and
• a fastener for drawing the first flange and second flange towards each other;
• wherein the adapter includes a shoulder extending from the tubular member, the first flange engaging the shoulder;
• wherein the adapter includes a guiding surface having an angle with respect to the longitudinal axis, the retainer includes an inlet surface having the angle with respect to the longitudinal axis;
• wherein the adapter includes an o-ring groove formed on an exterior surface thereof for receiving an o-ring for sealing against the retainer;
• wherein the adapter includes an adapter sealing surface, the sealing member includes a sealing surface, the adapter sealing surface and sealing surface coacting to compress tubing therebetween;
• wherein the body includes an o-ring groove formed on an exterior surface thereof for receiving an o-ring for sealing against the retainer;
• wherein the body includes a frusto-conical annular recess at a distal portion of the second body end, the ferrule positioned in the frusto-conical annular recess, the frusto-conical annular recess has a recess surface having a first angle a relative to a longitudinal axis, the ferrule having a tapered surface, a portion of the tapered surface having a second angle a relative to a longitudinal axis, the second angle less than the first angle.
