Abstract
A bushing including a first annular internal rib adapted and configured to engage a corrugation valley of corrugated tubing and a second annular internal rib adapted and configured to press against a conductive layer surrounding the corrugated tubing is provided. The second annular internal protrusion has a rounded, substantially non-piercing profile. Also provided is a sealing device for connecting a length of tubing. The sealing device includes a body member defining a sleeve portion and the bushing as described herein adapted and configured to be received in the sleeve portion. Also provided is a length of tubing including: an inner tubing layer and the fitting as described herein engaged with the inner tubing layer.

A bushing comprising:
- a tapered outer profile having a proximal end having a smaller outer diameter than a distal end;
- a first annular internal rib:
- positioned proximal to the proximal end;
- and
- adapted and configured to engage a corrugation valley of corrugated tubing;
- a second annular internal rib:
- positioned distally relative to the first annular internal rib with respect to the proximal end;
- having a larger internal diameter than the first annular internal rib;
- adapted and configured to press against a conductive layer surrounding the corrugated tubing;
- and
- having a rounded, substantially non-piercing profile;
- and
- a third annular internal rib:
- positioned distally relative to the first annular internal rib and the second annular internal rib with respect to the proximal end;
- having a larger internal diameter than the second annular internal rib;
- and
- adapted and configured to press against an external jacket surrounding the conductive layer.
