Thomas & Betts XJG44-EMT – Frequently Asked Questions

1) What is an EMT expansion coupling for, and do I need one on my conduit run?
An expansion coupling joins two lengths of EMT while letting the run grow and shrink with temperature instead of buckling or pulling connections apart. The Thomas & Betts XJG44-EMT gives 4 inches of travel on 1-1/4 inch EMT. You need one where a run crosses a building expansion joint, or on long runs exposed to real temperature swing (outdoor runs, unconditioned industrial space, rooftop feeds to HVAC equipment). Inside a conditioned building on a short run, a standard EMT coupling is all you need.
2) Is a ductile iron expansion coupling strong enough for an industrial conduit run?
The body is ductile iron, which takes mechanical abuse and impact better than a die cast fitting, which is why these get specified for industrial and outdoor runs where a fitting can get hit or loaded. That covers the mechanical side. Bonding is separate: an expansion fitting moves, so the sliding joint is not a substitute for an equipment ground path, and a bonding jumper across the fitting is the normal practice.
3) How much movement does the 4 inch travel actually give me, and where do I set the coupling?
Four inches is the total travel of the fitting, not four inches in each direction. Set it during install so the remaining travel matches the direction the run will move: if you are installing on a cold day, leave most of the travel available for expansion; on a hot day, leave room for contraction. Splitting it and centering the fitting is the safe default when you don't know the temperature extremes.
4) Does the XJG44-EMT expansion coupling handle side-to-side misalignment or only in-line movement?
It is a straight-line expansion fitting, so it takes axial movement along the conduit, the 4 inches of travel. It is not a deflection or combination expansion/deflection fitting and should not be relied on for lateral shift or angular movement across a seismic joint. Openings that move in more than one direction need a fitting rated for deflection as well.
5) Do I still need to support the conduit on both sides of an expansion fitting?
Yes, and how you support it decides whether the fitting works. The run has to be anchored on one side so movement is forced into the coupling, and supported with straps that let the conduit slide on the moving side. Clamp both sides tight and the 4 inch travel never gets used, the conduit just stresses the fitting and the boxes at either end.
6) What is the manufacturer part number for the Thomas & Betts 1-1/4 inch EMT expansion coupling?
XJG44-EMT is the Thomas & Betts catalog number for the 1-1/4 inch EMT expansion coupling with 4 inch travel. The XJG44 designation covers the 4 inch travel body, and the EMT suffix is the raceway type the ends are made for.
