Claim:
An electric metal tube coupler assembly comprising: a coupler body having a bore extending therethrough and having first and second opposed end openings adapted to receive an electric metal tube; a first seal placed adjacent the first opposed end opening; an internal shoulder stop placed within the bore of said coupler body, wherein said internal shoulder stop extends radially into the bore; a ramp facing the second opposed end placed adjacent said internal shoulder stop; and a second seal placed adjacent said ramp so that said ramp is between said internal shoulder stop and said second seal; a flexible grounding strap externally connected to said coupler body and capable of attaching to the electric metal tube when the electric metal tube is inserted into said coupler body; and a grounding spring placed internally within the bore of said coupler body so that the electric metal tube when placed within said coupler body is free to slide on said grounding spring, whereby the ramp aids in centering the electric metal tube within said coupler body improving contact with said second seal when the electric metal tube is secured to said coupler body and said flexible grounding strap and said grounding spring provides enhanced electrical grounding or continuity.
