IPEX ELECTRICAL INC 029012 Super Duct Coupling 3 in Push Fit 76.2 mm ID PVC

These couplings make it easy to rapidly assemble cut lengths of concrete-encased Super Duct. Push the spigot end of the duct into the fitting socket and hammer lightly against a piece of wood located at the end of the coupling or pipe until end of duct butts up against the inside shoulder of the fitting. Push-fit couplings are not watertight and are only recommended for use when encased in concrete.
