Allied Tube & Conduit CK50RKON – Frequently Asked Questions
1) Will the Allied Tube & Conduit CK50RKON compression coupling work on 1/2 inch EMT?
Yes. The CK50RKON is a 1/2 inch compression coupling, so it joins two lengths of 1/2 inch trade size EMT. Compression couplings grip the tubing on a shoulder with a gland ring and nut, so no threading of the conduit is required, just cut square, deburr, and tighten.
2) Can I use a compression coupling in a concrete pour, or do I need a rain-tight fitting?
The CK50RKON is rated concrete tight, so it can be embedded in poured concrete slabs and walls without grout working into the raceway. That is the usual reason a contractor picks a compression coupling over a set screw coupling, which is not concrete tight.
3) Compression coupling or set screw coupling for 1/2 inch EMT?
Use a set screw coupling for dry, accessible indoor runs where nothing wet or structural is involved. Step up to a compression coupling like the CK50RKON when the fitting will be in concrete or in a damp location, since it is concrete tight and the set screw type is not. Compression takes a little longer to install but seals on the tube wall.
4) Is the CK50RKON coupling protected against corrosion for damp indoor locations?
The body is zinc plated to resist corrosion, and the walls are heavy steel. That plating suits it to normal indoor and damp-location work; it is not a substitute for a fitting specified for direct burial or corrosive process environments.
5) What exact part number should I order for the 1/2 inch Allied compression coupling?
Order Atkore Allied Tube & Conduit part number CK50RKON. That is the 1/2 inch steel compression coupling; the catalogue number carries the 50 to denote the 1/2 inch trade size.
6) Does the CK50RKON come with the compression nuts and rings, or do I buy those separately?
A compression coupling is supplied as a complete assembly, body with a gland ring and compression nut at each end, so nothing extra is needed to join two pieces of 1/2 inch EMT. You will still need your own conduit reamer and a wrench to draw the nuts down tight.
