Allied Tube & Conduit SEC350KON – Frequently Asked Questions

1) Can the Allied Tube & Conduit SEC350KON couple threaded rigid conduit to unthreaded EMT?
That is exactly what the SEC350KON is built for. It is a 3-1/2 inch three-piece compression coupling that joins threaded IMC or GRC to threaded or unthreaded EMT, IMC or GRC. The same fitting also handles unthreaded to unthreaded, so you can transition between conduit types without cutting new threads in the field.
2) What size conduit does the SEC350KON compression coupling take?
3-1/2 inch. The SEC350KON is a single-size steel fitting, so both ends land on 3-1/2 inch conduit, whether that run is EMT, IMC or GRC.
3) Do I have to take the conduit run apart to install this Allied Tube coupling?
No. The three-piece design of the SEC350KON lets you make the connection without disassembling the fitting or breaking down the run, which is the point of the Super Fitting line - it speeds up repairs and tie-ins on conduit that is already hung.
4) Can one SEC350KON replace the rigid hubs and separate fittings I normally stock for 3-1/2 inch conduit?
For 3-1/2 inch work, yes - Allied describes the Super Fitting as one fitting that replaces various rigid HUBs and fittings. For an MRO or distributor stocking program that means a single line item covers threaded-to-threaded, threaded-to-unthreaded and unthreaded-to-unthreaded connections in that trade size instead of three separate SKUs.
5) Is the Atkore Super Fitting SEC350KON steel or die-cast?
Steel. The SEC350KON is a steel compression coupling from Allied Tube & Conduit's Super Fitting line, so it matches the material of the steel EMT, IMC and GRC it connects.
6) What is the manufacturer part number for the 3-1/2 inch Allied Super Fitting compression coupling?
SEC350KON, from Allied Tube & Conduit (Atkore). If you are cross-referencing on a submittal, that number covers the 3-1/2 inch three-piece steel compression coupling for threaded and unthreaded conduit.
