Crouse-Hinds 657RT – Frequently Asked Questions

1) Can I use Crouse-Hinds RT compression connectors outdoors on exposed EMT?
Yes. The RT series compression connectors are raintight, so they hold up where the run is exposed to weather. The catch is the area classification: they're rated for ordinary, non-hazardous locations only. Wet is fine, classified (hazardous) areas are not, and you'd need a fitting listed for that class and division instead.
2) What trade sizes do the Crouse-Hinds RT EMT connectors come in?
Nine trade sizes, 1/2 inch through 4 inch: 650RT (1/2), 651RT (3/4), 652RT (1), 653RT (1-1/4), 654RT (1-1/2), 655RT (2), 656RT (2-1/2), 657RT (3), and 659RT (4). Order by the EMT trade size you're running, not by the conduit's outside diameter.
3) Will a compression connector work on rigid or IMC conduit?
No. These are EMT fittings. Compression connectors grip the smooth outside wall of thinwall tubing; rigid and IMC are threaded, heavier-wall conduit and take a threaded coupling or a fitting made for that conduit type. Using an EMT compression connector on rigid is not a listed installation.
4) Should I use a compression connector or a set screw connector on EMT?
Set screw fittings are cheaper and fine for dry interior work, but they are not raintight. If the run is outdoors, in a wet location, or entering a weatherproof enclosure, you want the compression style like the RT series, which is listed raintight. Indoors in a dry mechanical room, either works and set screw is faster. The dividing line is water, not conduit size.
5) Do I need to thread the EMT to use these connectors?
No threading, no dies, no cutting oil. The RT connectors are threadless on the conduit side: you cut the EMT square, ream it, slide the tubing into the connector body and tighten the compression nut. That's the whole install, which is why compression is the go-to for field runs where you're making up conduit on a lift or in a ceiling.
6) Are these Crouse-Hinds connectors insulated throat?
No, the RT compression connectors are non-insulated. Where the job or the inspector calls for an insulated throat, you either specify an insulated-throat connector or add a plastic insulating bushing at the connector. Ream the EMT either way before pulling conductors.
7) Are Crouse-Hinds RT compression connectors code compliant for commercial work?
They're built to NEC and CEC standards, which covers both US and Canadian jobs. The compliance limit to watch is location: ordinary, non-hazardous only. That covers commercial, industrial, and multi-family conduit runs including weather-exposed ones, but not classified areas.
8) Will a raintight compression connector bond the conduit run, or do I need a bonding jumper?
Steel body, steel compression ring, metal-to-metal on the EMT and a locknut into the box, so the connector carries the equipment ground path the same way the rest of a steel EMT system does. Where a bonding jumper is separately required (concentric or eccentric knockouts, for example), that requirement comes from the enclosure, not from the fitting.
9) Can I use these to bring EMT into a NEMA 3R panel or outdoor junction box?
That's the intended use. Straight configuration and raintight construction means it lands directly on a knockout in a weather-exposed enclosure without a fitting change. Pick the connector by the trade size of the EMT and match the knockout, 1/2 inch through 4 inch across the RT range.
10) Do these EMT connectors come with a locknut?
A compression connector is a two-part assembly: the body with its compression nut and gland ring on the conduit side, and a locknut that secures it through the enclosure knockout. Steel throughout. If the enclosure needs a sealing ring or gasket for its own rating, that's separate hardware you'd order alongside.
11) Are the steel bodies better than die-cast for a job spec that calls out steel EMT fittings?
The RT series is steel, which is what a spec calling for steel EMT fittings is asking for. Many commercial and institutional specs exclude die-cast zinc on exposed or outdoor runs because of how it handles mechanical stress, so if your drawing says steel compression connector, raintight, this matches on all three points.
