Bridgeport Fittings 4372-LT – Frequently Asked Questions

1) What does the Bridgeport 4372-LT coupling actually connect?
It joins 1 inch rigid conduit (GRC) or IMC on one end to 1 inch metallic liquid tight flex on the other, in a single fitting. Both ends are the same trade size, 1 inch, so you are not stepping sizes across the transition. Use it where a hard raceway run has to pick up flexible liquid tight going into a motor, rooftop unit, or vibrating equipment.
2) Is this Bridgeport combination coupling rated for outdoor and wet locations?
Yes. The liquid tight combination coupling is UL Listed raintight with a NEMA FB-1 rating, under UL file E9391, so it is built to keep water out of the inner raceway. That covers rooftop, exterior wall, and other wet location transitions where a standard dry-location combination coupling would not hold up.
3) Can I use this coupling with non-metallic liquid tight?
No. The 4372-LT is built for metallic liquid tight flex on the flexible side. Non-metallic liquidtight uses a different connector body and sealing arrangement, so you need a fitting specified for LFNC rather than this one.
4) Will a 1 inch raintight combination coupling fit in a tight junction box or panel knockout area?
The fitting is 1.875 inches long and 1 inch wide, so it takes under two inches of straight run to make the transition. That is usually enough clearance behind equipment or in a congested rack, but measure your gap before you cut the conduit, since the rigid end still needs thread engagement.
5) What material and finish is the Bridgeport 4372-LT, and will it hold up in a corrosive environment?
Steel construction with a zinc plated finish. Bridgeport also calls out malleable iron as its heaviest-duty combination coupling design for superior strength and rigidity. Zinc plating gives ordinary outdoor and damp-location corrosion resistance; for chemical or coastal exposure beyond that, spec a coated or stainless fitting instead.
6) I need this same transition in 3/4 inch, not 1 inch. Does Bridgeport make other sizes?
Yes. Bridgeport's combination couplings run trade sizes 3/8 inch through 2 inch. The 4372-LT is the 1 inch version, with 1 inch on the rigid/IMC side and 1 inch on the liquid tight side. Order by the trade size of the raceway you are actually joining, not by the wire fill.
7) Is the Bridgeport 4372-LT made in the USA?
Bridgeport Fittings is an American manufacturing company, but this particular coupling has a country of origin of China. If your project carries a domestic-content requirement, verify against that spec before you submit it.
8) How much does the Bridgeport 1 inch raintight combination coupling weigh for a bulk order?
Catalog weight is 2.4 lbs. Worth knowing if you are pulling a hundred of them for a job cart or figuring freight on a large institutional order, since malleable iron fittings add up fast compared with die cast.
