The Duraline HDPE Coupler, 1.25 in (vendor part 2005385, Millennium part 523423), joins sections of 1.25-inch HDPE duct into a continuous run, keeping the joint water-tight under the pressure and tension of cable blowing operations. Conduit crews use it wherever duct reels run out mid-trench or bore on a fiber build, avoiding a costly re-pull. The mechanical connection installs without heat fusion equipment, speeding up field joints. Pair it with duct plugs and Mor Clamps sized for the same 1.25-inch duct.
