Bridgeport Fittings BF-251 – Frequently Asked Questions

1) Can Bridgeport steel EMT compression connectors be used in a concrete pour?
Yes. These compression type steel EMT connectors are rated concrete-tight, so they hold a seal against wet concrete and debris where the EMT enters a box or enclosure. That is the standard use for them in slab and deck work. If your run is in a wet or outdoor location, note that concrete-tight is what is stated here, not raintight.
2) What trade sizes do Bridgeport EMT compression connectors come in, and which part number is which?
Ten trade sizes, 1/2 inch through 4 inch: 1/2 in is part 250, 3/4 in is 251, 1 in is 252, 1-1/4 in is 253, 1-1/2 in is 254, 2 in is 255, 2-1/2 in is 256, 3 in is 257, 3-1/2 in is 258 and 4 in is 259. Order by EMT trade size, and the connector matches the corresponding knockout in the box.
3) Are these EMT connectors UL Listed for a permit inspection?
They are UL Listed under File No. E24001 and carry a NEMA FB-1 rating, and they meet the bonding requirements for the connection. That is the paperwork an inspector or a spec writer will be looking for on an EMT-to-box termination.
4) For a wet or liquidtight flexible conduit run, should I use these Bridgeport EMT compression connectors or something else?
Use a liquidtight fitting instead. The RACO 4734 is a SWIVEL-LOK Series 1 inch Type B liquidtight multi-position connector in nylon, built for liquidtight flexible conduit. The Bridgeport steel compression connectors are rated concrete-tight for EMT-to-box terminations and carry a NEMA FB-1 rating, so they belong on rigid EMT runs, not on liquidtight flex.
5) Should I use steel compression connectors or die-cast set-screw connectors for EMT?
Compression is the choice when the connection has to be concrete-tight, as in a slab pour or a poured deck. Set-screw fittings are quicker and cheaper but are not concrete-tight. These Bridgeport connectors are steel with a zinc electro-plate finish rather than die-cast zinc, which is what most commercial and industrial specs call for on exposed or embedded runs.
6) Does a compression connector need a locknut, or is it included with the fitting?
A compression connector goes through the box knockout and is secured with a locknut on the inside, and the compression nut and gland ring make the seal on the EMT side. Verify the pack contents for the size you are ordering so you are not short a locknut on a large 3 inch or 4 inch termination.
7) Can I standardize one EMT connector type across a whole building's electrical rough-in?
Yes, and that is the usual approach for an MRO or facility standard. The same steel compression family covers 1/2 inch through 4 inch EMT (parts 250 through 259), one finish, one UL file (E24001) and one NEMA FB-1 rating, so a single stocked line covers branch circuits through feeders without mixing fitting types across the job.
8) Is a 3M SC0001 stem connector an alternative to a steel EMT compression connector?
No. The 3M SC0001 is an SC Series stem connector for conductors up to 35 kV in 2 and 1 AWG, so it is a conductor termination, not a raceway fitting. The Bridgeport product is a steel connector with zinc electro-plate finish that joins EMT to a box or enclosure. A job needing both would order them separately.
9) Will a steel EMT connector hold up better than zinc die-cast in a damp mechanical room?
The body is steel with zinc plating, which gives corrosion resistance plus the mechanical strength of steel, so it takes abuse in mechanical rooms, parking structures and industrial plants better than a brittle die-cast body. For genuinely wet or corrosive environments, confirm the location classification against what your spec allows; the rating stated on these is concrete-tight.
