Allied Tube & Conduit CK75RKON – Frequently Asked Questions

1) Can I use a compression coupling in a concrete pour, or do I need a different fitting?
Concrete tight is stated for this 3/4 inch coupling, so it can be used where the fitting will be embedded in poured concrete. That is the main reason installers pick compression over a set screw coupling, which is not rated for concrete. It is not a rain tight or wet location claim, just concrete tight.
2) Compression or set screw coupling for 3/4 inch EMT, which should I use?
Use the compression type, like the CK75RKON, when the connection will be buried in concrete or needs a tighter mechanical grip, since it is rated concrete tight. Set screw couplings are quicker and cheaper for dry indoor exposed runs but are not concrete tight. Both join the same 3/4 inch EMT, so it comes down to where the run goes.
3) Is this coupling corrosion resistant enough for a parking garage or damp mechanical room?
The body is zinc plated to resist corrosion and built with heavy steel walls, which is the normal spec for interior, garage, and mechanical room EMT work. For directly wet or corrosive outdoor exposure, a rain tight compression fitting or a different raceway system is the right call.
4) Do I need any extra parts to make up a joint with the CK75RKON?
No. A compression coupling ships complete with its compression nuts and rings, so the only thing you supply is the cut and reamed 3/4 inch EMT. Tighten the nuts with a wrench, not by hand, or the joint will not hold electrical continuity or stay concrete tight.
5) What is the exact manufacturer part number for this Allied 3/4 inch compression coupling?
The part number is CK75RKON, from Atkore Allied Tube & Conduit. It is a single model, a 3/4 inch steel compression coupling, so there are no finish or size variations to specify when ordering.
