Thomas & Betts 8120 – Frequently Asked Questions

1) Can I use a compression coupling to join conduit when I can't thread the ends?
That is exactly what a threadless compression coupling is for. The Thomas & Betts coupling makes up on plain, unthreaded conduit ends by compressing onto the raceway, so you can cut to length in the field and join two runs without cutting threads or rotating either piece. Where both ends are already threaded and one can be turned, a standard threaded coupling is the simpler choice.
2) Can I repair a broken conduit run in the middle without pulling the whole length?
Yes, and that is the common use for a threadless coupling. Because neither piece has to be turned to make up the joint, you can cut out a damaged section and splice the new piece in place with couplings on both ends. Thomas & Betts offers this style in 1/2 inch and 1-1/2 inch.
3) Is this coupling steel or aluminum, and will it hold up in an industrial plant?
Malleable iron. That is the heavier-duty body material for conduit fittings, and Thomas & Betts lists these for commercial building, industrial facility, and manufacturing electrical installations. Malleable iron fittings are normally paired with rigid or IMC steel conduit rather than aluminum raceway, since mixing dissimilar metals in a wet location invites galvanic corrosion.
4) Does a compression coupling keep the ground path through the conduit run?
The compression connection is a mechanical grip that maintains electrical continuity across the joint, so the raceway stays continuous as an equipment grounding path where the conduit system is used for grounding. It is a dry-location style mechanical fitting, not a raintight or hazardous-location fitting, so match the fitting type to the environment your run passes through.
5) What is the difference between a compression coupling and a set screw coupling?
A compression coupling seals and grips by drawing a ring down onto the conduit with a tightened nut, which spreads the clamping force around the full circumference. A set screw coupling bites the raceway with screws at one or two points. Both are threadless and both join unthreaded ends; the compression style is the one Thomas & Betts builds here in malleable iron for commercial and industrial work.
