Allied Tube & Conduit SK50RKON – Frequently Asked Questions
1) Can a set screw EMT coupling be used in a concrete pour?
Only if it is taped. The Allied set screw coupling is rated concrete tight when taped, so wrapping the joint before the pour is what keeps wet concrete out of the raceway. Untaped, a set screw fitting is not a concrete tight connection. If you want a fitting that is concrete tight without taping, use a compression (raintight) EMT coupling instead.
2) Do I have to buy the set screws separately for this EMT coupling?
No, the screws come installed. The 1/2 inch SK50RKON ships with pre-set and staked tri-head screws, so there is nothing loose to source or drop on the job. You need a tri-head driver rather than a flat blade or hex key to tighten them.
3) Set screw or compression coupling for 1/2 inch EMT, which should I use?
Set screw fittings like the SK50RKON are the standard choice for dry indoor and exposed interior work, and they go together faster. Compression fittings are what you specify for wet or damp locations where a raintight connection is required. For a slab pour, the set screw type works but only when the joint is taped.
4) Is this a steel EMT coupling or a die cast one?
Steel. The Allied Tube & Conduit set screw coupling is built with heavy steel walls, which is what holds up to being stepped on or struck on a rough-in before the walls close. Die cast fittings crack under that kind of abuse.
5) Why do the larger Allied set screw couplings have hex screws instead of tri-head?
Allied uses pre-set staked tri-head screws on 1/2 inch through 2 inch fittings, and switches to hex head screws on 2-1/2 inch through 4 inch. The SK50RKON, being 1/2 inch, takes the tri-head screws. If you are standardizing a crew's tool kit across trade sizes, plan on a tri-head driver for the small sizes and a nut driver for the large ones.
