Allied Tube & Conduit SEC400KON – Frequently Asked Questions

1) Can the Allied Tube & Conduit SEC400KON couple threaded rigid conduit to unthreaded EMT?
That is exactly what the SEC400KON is built for. It's a 4 inch three-piece compression coupling that joins threaded IMC or GRC to threaded or unthreaded EMT, IMC, or GRC. Threaded to threaded, threaded to unthreaded, and unthreaded to unthreaded are all covered by the same fitting, so you don't need a separate adapter on the transition.
2) What size conduit does the SEC400KON compression coupling take?
It's the 4 inch size in the Allied Tube & Conduit Super Fitting compression coupling line. One fitting handles 4 inch EMT, IMC, and GRC, so it covers the run whether the ends are threaded or plain.
3) Do I have to take the coupling apart to install it on a conduit run?
No. The three-piece Super Fitting design installs without disassembling the fitting, which is the point of it on retrofit and repair work where you're joining into an existing 4 inch run and can't rotate the pipe.
4) Can one SEC400KON replace the rigid hubs and adapters I normally stock for 4 inch conduit?
That's the intent of the Super Fitting. Allied lists it as one fitting replacing various rigid HUBs and fittings, so a single 4 inch part covers threaded and unthreaded combinations in EMT, IMC, and GRC instead of several separate SKUs on the truck or the storeroom shelf.
5) What is the manufacturer part number for the 4 inch Allied Super Fitting compression coupling?
Order it as SEC400KON from Allied Tube & Conduit (Atkore). That number is the 4 inch three-piece steel compression coupling; the size is encoded in the 400 in the middle of the part number.
6) Is the SEC400KON a steel fitting or a die cast one?
Steel. It's described as a steel Super Fitting compression coupling, which is what you want joining 4 inch GRC or IMC where the fitting has to carry the mechanical load of the run.
