ABSTRACT:
A coupler for electrically-isolating two conductive sections of fluid-passing line includes two nonconductively-interconnected pieces of tubing for insertion in the line. The pieces of tubing each have a divergently-flared end, and the flared ends are nonconductively-interconnected within two dielectric wafers. Each wafer has a tapered hole extending through it that matches the flared ends and enlarges to a face on the wafer. The flared ends are each bonded within a separate one of the tapered holes in a position recessed from the face with the flare of the end paralleling the taper of the hole, and the faces are bonded together with the larger ends of the tapered holes aligned and the flared ends sealed in fluid communication with an electrically-nonconductive gap between them.
