Crouse-Hinds CRS-657 – Frequently Asked Questions

1) What trade sizes do the Crouse-Hinds steel EMT compression connectors come in?
Ten trade sizes, 1/2 inch through 4 inch: 1/2 (650S), 3/4 (651S), 1 (652), 1-1/4 (653), 1-1/2 (654), 2 (655), 2-1/2 (656), 3 (657), 3-1/2 (658) and 4 inch (659). Order by the EMT trade size you are running, not the wire count, and the connector matches that tubing size one for one.
2) Can I use these Crouse-Hinds compression connectors on rigid or IMC conduit?
No. These are built for EMT (electrical metallic tubing) only. The compression gland grips the thin wall of EMT; rigid and IMC are threaded conduit and need a threaded coupling or a threaded hub fitting instead. Flexible conduit needs its own squeeze or screw-in connector.
3) Are these EMT connectors rated for wet locations or outdoor use?
Only ordinary, non-hazardous locations are stated for these steel compression connectors. No raintight or wet-location rating is carried here, so for exposed outdoor runs or damp areas specify a fitting marked raintight. They are also not for classified hazardous areas.
4) Should I use compression or set-screw EMT connectors?
Compression, like these Crouse-Hinds steel fittings, uses a gland nut and ring that squeezes the full circumference of the tubing, so the joint stays tight under vibration and pull. Set-screw connectors are quicker and cheaper and are fine for dry interior work. Pick compression where the run is exposed, subject to movement, or where the inspector wants the more secure mechanical joint. Note these are rated for ordinary, non-hazardous locations.
5) Do I need an insulated throat bushing with these Crouse-Hinds EMT connectors?
These are the non-insulated version, so the throat is bare steel. If your conductor insulation or the local inspector calls for a protected throat (common on larger sizes pulling THHN), add a plastic bushing or specify an insulated-throat connector. The non-insulated steel body does carry grounding continuity through the fitting.
6) Will these connectors satisfy an electrical inspector for commercial work?
They are built to NEC/CEC standards for ordinary, non-hazardous locations, which covers typical commercial, institutional and residential EMT work: panel feeds, office and retail branch circuits, school and healthcare interior runs. Anything in a classified hazardous area needs a fitting listed for that classification.
7) How much room do I need behind the box for these EMT compression connectors?
Allow about 1.5 inches of depth for the fitting. Straight-body design, so the EMT comes into the knockout in line, with no offset or angle, which is what you want for clean stub-ups into a panel or box. Tight ceiling cavities or shallow back-boxes, measure first.
8) Are these steel or die-cast zinc EMT connectors?
Steel. That matters for MRO buyers standardizing a facility: steel compression fittings hold up better to impact and over-torque than die-cast zinc, which is why they get specified on industrial and exposed runs. All ten trade sizes from 1/2 inch to 4 inch share the same steel compression construction.
9) Do these EMT connectors come with locknuts?
Crouse-Hinds compression connectors of this type are supplied as the connector body with its compression nut and ring for the tubing side. Plan on the locknut for securing the fitting into the box knockout, plus a bushing if you want a protected throat, since the fitting itself is non-insulated.
