Abstract
A light walled circular metallic conduit including a first conduit member and a second conduit member. An expanded section is at one end of the first conduit member and an end of said second conduit member is snugly telescoped within said expanded section of said first conduit member. The expanded section has external threads thereon and a nut is provided which is internally threaded. Inside the nut is a split ring. The nut encircles a seal. Upon tightening the nut the split ring bites into the second conduit member. A skirt is affixed to the nut and includes a finger which extends into a gap between the nut and the second conduit member so as to prevent water from leaking into said gap and into the interior of said first and second conduit members.
