Bridgeport Fittings 433-SLT – Frequently Asked Questions

1) What trade sizes do the Bridgeport malleable iron liquid tight straight connectors come in?
Five trade sizes: 1-1/4 inch (433-SLT), 2 inch (435-SLT), 2-1/2 inch (436-SLT), 3 inch (437-SLT) and 4 inch (439-SLT). All are the straight body style with standard (non-insulated throat) build, so for smaller runs under 1-1/4 inch you'd be looking at a different fitting line.
2) Can I use these liquid tight connectors on outdoor or washdown equipment?
Yes. The malleable iron liquid tight straight connectors are rated NEMA Type 2, 3, 3R, 4 and 12 and meet NEC requirements for wet locations. The NPT threads, knockout gasket and internal sealing ring are what make the enclosure entry water tight, so the gasket has to go on the outside of the knockout for that rating to hold.
3) Will these fit non-metallic liquidtight conduit?
No. These Bridgeport straight connectors are made for metallic liquid tight conduit (LFMC). Non-metallic liquidtight (LFNC) uses a different ferrule profile and needs a connector listed for that conduit type.
4) Are Bridgeport liquid tight connectors UL listed for inspection?
They are UL Listed under file E9391 and carry a NEMA FB-1 rating, which is the standard an inspector will look for on a fitting used in a wet location entry.
5) Can I use a Thomas & Betts 306 Tite-Bite connector instead of a Bridgeport liquid tight straight connector?
No, they are not interchangeable. The Thomas & Betts 306 is a straight Tite-Bite connector for 1 inch FMC, meaning standard flexible metal conduit, and it is non-insulated. The Bridgeport straight connectors are made for metallic liquid tight conduit and use NPT threads with a knockout gasket and internal sealing ring to keep water out, which is what earns them the NEMA TYPE 2, 3, 3R, 4 and 12 wet-location use described for them. If the run is dry-location FMC, the TB 306 is the fitting type; if the conduit is liquidtight and the location is wet, use the Bridgeport liquid tight connector in the matching trade size.
6) What is the difference between the Bridgeport 433-SLT liquid tight connector and the RACO 4734 SWIVEL-LOK connector?
Both terminate liquidtight flexible conduit, but they are built differently and cover different trade sizes. The Bridgeport straight liquid tight connectors are malleable iron with a zinc electro-plate finish, with the smallest of the straight sizes at 1-1/4 inch and running up through 2 inch, 2-1/2 inch, 3 inch and 4 inch. The RACO 4734 is a 1 inch Type B liquidtight connector made of nylon, and it is a multi-position design rather than a fixed straight body. Choose the Bridgeport malleable iron connector when you need a metal body on larger trade sizes; the RACO 4734 covers 1 inch in a nonmetallic body and lets you angle the conduit run.
7) Is a malleable iron liquid tight connector worth it over a die cast or nylon one?
Malleable iron is Bridgeport's heaviest-duty option, chosen for strength and rigidity on the large trade sizes and rough industrial work where a fitting takes physical abuse. Zinc electroplate handles corrosion. If the run is light duty or needs to swing to an angle, a nylon multi-position fitting like the RACO 4734 SWIVEL-LOK in 1 inch is the other direction entirely.
8) How do these Bridgeport liquid tight straight connectors go together on the conduit?
Slide the compression nut and sealing ring over the conduit, then thread the ferrule into the conduit end and draw the nut up. The body threads into the enclosure knockout on NPT threads with the knockout gasket between fitting and box.
9) Is the RACO 232MSCM box connector an alternative to a Bridgeport liquid tight connector?
No. The RACO 232MSCM is a 4 inch square welded box, 2-1/8 inches deep, with an M bracket and an integral STAB-IT connector for cable entry; it is the enclosure itself, not a conduit fitting. The Bridgeport product is a connector that terminates metallic liquid tight conduit into an enclosure knockout, offered in 1-1/4, 2, 2-1/2, 3 and 4 inch trade sizes with a zinc electro-plated malleable iron body. If you are landing liquidtight conduit into a box, you still need the Bridgeport connector regardless of which box is on the job.
10) Do these connectors have an insulated throat?
The malleable iron straight connectors are offered in the standard, non-insulated configuration across all five sizes. If your spec calls for an insulated throat on conductors entering the box, specify a fitting built with a plastic throat insert instead.
11) Does the 3M SC0001 stem connector do the same job as a Bridgeport liquid tight connector?
No. The 3M SC0001 is a stem connector rated up to 35 kV for 2 and 1 AWG conductors, so it joins conductors in a medium-voltage splice or termination. The Bridgeport liquid tight straight connectors are conduit fittings that attach metallic liquid tight conduit to an enclosure with NPT threads, a knockout gasket and an internal sealing ring. The two are used at different points in the same installation and neither substitutes for the other.
