Bridgeport Fittings 1520-DC – Frequently Asked Questions

1) What does an offset nipple actually do, and when would I use one instead of a regular nipple?
Bridgeport's zinc die cast offset nipple shifts the axis of the raceway by 3/4 inch, so you can join two boxes or conduit runs whose centerlines do not line up. A straight nipple only works when the two threaded hubs are dead in line. Typical case: two panels or boxes mounted back to back or side by side where the knockouts are offset. Note the offset amount is 3/4 inch regardless of which trade size you order.
2) Can I use these Bridgeport offset nipples outdoors or in a wet location?
No. These offset nipples are rated dry location only, with a NEMA FB-1 rating. For outdoor, damp, or wet locations you need a fitting specifically listed for that environment. The zinc die cast body resists corrosion, but corrosion resistance is not a wet-location listing.
3) What trade sizes do the Bridgeport zinc die cast offset nipples come in, and which part number do I order?
Six trade sizes, each with its own part number: 1/2 inch is 1520-DC, 3/4 inch is 1521-DC, 1 inch is 1522-DC, 1-1/4 inch is 1523-DC, 1-1/2 inch is 1524-DC, and 2 inch is 1525-DC. Order by the trade size of the conduit or knockout you are connecting to, not by the 3/4 inch offset dimension.
4) Are these offset nipples UL listed for an inspected commercial job?
Yes. The zinc die cast offset nipples are UL listed under file E9391 and carry a NEMA FB-1 rating, which is what an inspector will look for on a dry-location raceway fitting.
5) What thread type is on the Bridgeport offset nipple, and will it seal against a threaded hub?
The threads are NPSM (straight mechanical pipe thread). Engaged properly with a mating male or female thread, they give a pressure-tight, vibration-resistant joint. NPSM is not a tapered NPT thread, so if your spec calls for a tapered thread seal on a pressurized or hazardous-location fitting, this is the wrong part.
6) Will a zinc die cast offset nipple hold up in a damp industrial space or a mechanical room?
The zinc die cast body is naturally corrosion resistant and finished ball burnished to a mirror smooth surface, which helps in humid indoor air. But the fitting itself is listed for dry locations only, so a mechanical room that sees condensation or washdown is outside what this part is rated for.
7) If two panel knockouts are more than 3/4 inch out of line, can I still use this fitting?
No. The offset is fixed at 3/4 inch on every size of this Bridgeport nipple, so it corrects that amount and nothing more. For a larger misalignment you need a length of conduit with offset bends, or a box/conduit body and short nipples to make up the difference.
8) Are these Bridgeport offset nipples made in the USA for a government or Buy American job?
Country of origin on the Bridgeport zinc die cast offset nipples is the United States, which is the data a public agency or institutional buyer needs for a domestic-preference submittal.
