Bridgeport Fittings BF-247 – Frequently Asked Questions

1) What trade sizes do Bridgeport set screw EMT couplings come in?
Bridgeport's steel set screw EMT couplings run eight trade sizes: 1/2 inch (cat. 240), 3/4 inch (241), 1 inch (242), 1-1/4 inch (243), 2 inch (245), 3 inch (247), 3-1/2 inch (248) and 4 inch (249). Order by the EMT trade size you are joining, not by the outside diameter of the tubing.
2) Can these set screw couplings be used in a concrete pour?
Yes. These steel set screw couplings are concrete-tight, so they can be encased in a slab or deck pour without concrete aggregate getting in and abrading conductor insulation. They are not rated raintight, so a wet or outdoor exposed run calls for a compression type fitting instead.
3) Are Bridgeport 240 series EMT couplings UL Listed for an inspected commercial job?
They are UL Listed under file E24001 and meet the NEMA FB-1 standard for electrical conduit fittings, which is what an electrical inspector or an institutional spec typically asks for on EMT fittings.
4) Do these couplings work with rigid conduit or IMC?
No. These are EMT couplings, made for electrical metallic tubing only. Rigid and IMC are threaded and take threaded couplings or a threaded-to-EMT combination coupling, so do not substitute a set screw EMT fitting there.
5) Set screw or compression EMT couplings, which should I use?
Set screw couplings like the Bridgeport 240 series are the faster, lower-cost choice for dry interior work and for concrete-tight applications, since they are rated concrete tight. Compression couplings are what you use where the run is wet, damp, or outdoors and needs to be raintight. Set screw also lets you break a joint later by backing the screws out, which compression does not.
6) Will steel set screw couplings hold up in a damp mechanical room or corrosive area?
The body is steel with a zinc electro-plate finish, which gives corrosion resistance for interior and industrial environments. Steel bodies also give you more mechanical strength than a die cast fitting on a long or supported run. For continuously wet or chemically aggressive locations, plan on a raintight compression fitting and appropriate coating.
7) How many set screws hold each end of the EMT in a Bridgeport 240 coupling?
Each end of the coupling is secured by tri-drive set screws that clamp the EMT in place, so both pieces of tubing are gripped independently. Tri-drive heads let you drive them with a flat blade, a Phillips, or a hex driver, which matters when you are working overhead off a ladder.
8) Can I standardize one fitting type across a whole building's EMT runs?
For MRO and facility standardization the 240 series covers 1/2 inch through 4 inch under a single UL file (E24001) and NEMA FB-1 rating, all in the same zinc plated steel construction. That lets a facility stock one family of couplings for branch circuit 1/2 and 3/4 inch work right up through 4 inch feeder runs.
