Atkore Allied Tube & Conduit RCK100KON 1" Threadless Rigid Compression Coupling

It joins 1 inch rigid conduit without threading either end. A standard threaded coupling needs both conduit ends cut and threaded, and it needs one of the runs to turn. The RCK100KON is a compression coupling, so it clamps onto plain-cut conduit in place. That is why it is called out for runs that are closely spaced, where there is no room to spin a length of pipe into a threaded coupling.

Yes. The coupling carries a neoprene gasket that makes the joint concrete tight, so it can be encased in a slab or deck pour without grout working into the conduit run.

It is the 1 inch size, for joining trade size 1 rigid metal conduit. One coupling makes one splice, so count your joints when ordering.

That is the situation it is built for. Because it clamps rather than threads, neither existing run has to be rotated or rethreaded. Cut out the damaged section, drop in the replacement length, and compress a coupling on each end. With threaded couplings you would need a union type fitting instead, since fixed conduit cannot be turned.

The body is zinc plated for corrosion resistance, which is the normal finish for rigid conduit fittings used indoors, in slabs, and in ordinary damp interior locations. For aggressive or direct-buried corrosive soil conditions, specify a fitting rated for that service instead.

Order by catalog number RCK100KON, the 1 inch threadless rigid compression coupling from Allied Tube & Conduit (Atkore). Compression couplings are sized to trade size, so match the number to the conduit trade size on your drawing, not to the outside diameter of the pipe.
