Atkore Allied Tube & Conduit RCK150KON 1-1/2" Threadless Rigid Compression Coupling

No. The Allied Tube & Conduit RCK150KON is a threadless compression coupling for 1-1/2 inch rigid conduit, so it joins cut, unthreaded ends. That is what makes it useful for field cuts and repairs where you cannot get a die on the pipe or cannot rotate a section to thread it in.

Yes. The RCK150KON carries a neoprene gasket that provides a concrete tight seal, so it can be used on runs being encased in slab or deck pours without wet concrete working into the raceway.

It is sized for 1-1/2 inch rigid conduit. Trade size 1-1/2 only, so a 1-1/4 or 2 inch run needs the matching coupling in that size instead.

A threaded coupling needs both conduit ends threaded and at least one section free to turn. In an existing run, a tight ceiling, or a field cut, neither is practical. The RCK150KON clamps onto plain-cut 1-1/2 inch rigid ends and pulls up with its compression nuts, which is why it is specified where conduit runs are closely spaced and there is no room to spin pipe.

The body is zinc plated to resist corrosion, which suits normal indoor and concrete-encased work. It is a plated steel fitting, not a stainless or PVC-coated one, so for aggressive chemical exposure or direct marine atmosphere you would want a coated or non-ferrous fitting instead.

It is an electrical fitting. The RCK150KON couples 1-1/2 inch rigid metal conduit carrying conductors; it is not a pressure-rated pipe coupling and should not be used on water or gas lines.
