초록 ▼

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.

1. 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; andadapted 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; andhaving a rounded, substantially non-piercing profile; anda 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; andadapted and configured to press against an external jacket surrounding the conductive layer. 2. The bushing of claim 1, wherein the second annular internal rib is spaced along the bushing such that the second annular internal rib aligns with a second corrugation valley of the corrugated tubing. 3. The bushing of claim 1, wherein the third annular internal rib is spaced along the bushing such that the third annular internal rib aligns with a third corrugation valley of the corrugated tubing. 4. The bushing of claim 1, wherein the bushing is a split bushing. 5. The bushing of claim 1, wherein the bushing is a two-piece bushing. 6. The bushing of claim 1, wherein the bushing includes two halves coupled by a living hinge. 7. The bushing of claim 1, wherein the bushing is fabricated from a conductive material. 8. The bushing of claim 7, wherein the conductive material is a metal. 9.
