Atkore Allied Tube & Conduit CKR-50KON 1/2" Raintight Compression Coupling

Yes. The CKR-50KON compression coupling is raintight in wet locations, so it can be used on exposed exterior EMT runs. It's also concrete tight, which means it holds up in poured slab and masonry applications where wet concrete would otherwise work into the joint.

It's a 1/2 inch coupling, sized for 1/2 inch conduit on both ends. One coupling joins two lengths of 1/2 inch EMT; for any other trade size you need the matching size in the CKR series.

Use compression where the run is exposed to weather or embedded in concrete, which is what the CKR-50KON is built for: raintight in wet locations and concrete tight. Set screw couplings are cheaper and faster but are dry location only, so they belong on indoor concealed or exposed interior runs. If the conduit goes outside, under a slab, or into a wet area, the compression fitting is the correct choice.

No threading and no locknut. A compression coupling slips over the cut conduit ends and seals when you tighten the compression nuts with a wrench, so the tubing just needs to be cut square and deburred. Nothing is required beyond a wrench.

Heavy steel walls, which is what you want for exposed conduit in garages, loading docks, and other areas where a fitting can get knocked. Combined with the concrete tight rating it's suited to slab and structure work.

Order Allied Tube & Conduit part number CKR-50KON. That is the 1/2 inch raintight compression coupling in the CKR series; the size is encoded in the 50 (1/2 inch), so adjacent trade sizes carry different numbers in the same series.

The blue nut is an identification feature. On a job where set screw and compression fittings are mixed in the same box, the blue nut lets an inspector or the next electrician tell at a glance that the joint is the raintight compression type rather than a dry-location set screw fitting.
