Arlington Industries 448 – Frequently Asked Questions

1) What trade sizes do Arlington plastic insulated bushings come in?
The Arlington insulated bushings run the full common conduit range: 1/2 inch (440), 3/4 inch (441), 1 inch (442), 1-1/4 inch (443), 1-1/2 inch (444), 2 inch (445), 2-1/2 inch (446), 3 inch (447), 3-1/2 inch (448) and 4 inch (449). You pick the bushing by the trade size of the conduit or the threaded fitting it threads onto, so a 3/4 inch EMT connector takes the 441. Each size is a separate part number, so a job with mixed runs needs more than one line on the order.
2) What does an insulated bushing actually do on a conduit run?
It threads onto the end of the conduit or connector inside the box and gives the conductors a smooth insulating throat to bear against instead of a cut metal edge. Arlington's version is molded plastic, so there is no metal at the point where the wire turns, which is where jacket damage happens on pulls. It is required on the terminations the code calls out for bushings, and it is cheap insurance anywhere a large conductor makes a hard bend coming out of a fitting.
3) Can I use a plastic bushing on the large conduit sizes, or does that need metal?
Arlington offers this plastic insulated bushing all the way up through 3-1/2 inch and 4 inch trade size, and the 105 degree C rating carries across the range. Where a job spec or the inspector calls for a metallic bushing with an insulated throat on the larger sizes, this all-plastic bushing is not that part and you want a metal insulated-throat bushing instead. For a straight insulating bushing on the conduit end, these cover the full 1/2 inch to 4 inch spread.
4) Will these bushings hold up in a hot mechanical room or on equipment that runs warm?
That is the case they are built for. The 105 degree C rating means the plastic keeps its insulating properties at elevated ambient temperatures where an unrated bushing can soften or become brittle, so they suit boiler and mechanical rooms, rooftop HVAC feeds, and process equipment terminations. Both UL and CSA Listed for that duty.
5) Are Arlington insulated bushings made in the USA?
Yes, Arlington Industries manufactures these bushings in the United States. That matters on public work and institutional jobs carrying domestic-content requirements, where the bushing is one of the small items that gets caught in a submittal review.
6) I need to order bushings for a whole building. How are Arlington 440 series bushings packaged?
They ship 100 to a pack, by size. For an MRO stockroom or a contractor standardizing a truck stock, the practical move is a pack of the sizes you actually run, most commonly 1/2 inch (440) and 3/4 inch (441), and single packs of the larger feeders. All sizes are the same gray plastic, so the stock looks consistent across the building.
