Crouse-Hinds CPR30 – Frequently Asked Questions

1) Will a Crouse-Hinds CPR2 compression coupling work on rigid steel conduit and IMC both?
Yes. The CPR2 series compression coupling is rated for both rigid steel and intermediate metal conduit, so on a run that transitions between the two you use the same fitting. It joins by compression rather than thread, which is what makes it useful where you cannot turn the conduit to thread it up, like a repair in the middle of a fixed run or a tie-in against an existing stub.
2) Can I use a Crouse-Hinds CPR2 coupling in a concrete pour?
That is what it is built for. The CPR2 compression coupling carries a concrete-tight rating, meaning it keeps wet concrete and debris out of the raceway during the pour. It is also malleable iron, which holds up to the abuse of being tied off and walked on before the deck goes down. Note the classification: ordinary and non-hazardous locations only. It is not a fitting for a classified area.
3) What trade sizes does the Crouse-Hinds CPR2 compression coupling come in?
Nine trade sizes, 1/2 inch through 4 inch: 1/2 (CPR21), 3/4 (CPR22), 1 (CPR23), 1-1/4 (CPR24), 1-1/2 (CPR25), 2 (CPR26), 2-1/2 (CPR27), 3 (CPR28) and 4 inch (CPR30). The part number runs sequentially by size, with the jump from CPR28 to CPR30 at the 4 inch. Order by the conduit trade size, not by the actual outside diameter.
4) Can I repair a rigid conduit run without cutting threads or turning the pipe?
A threadless compression coupling is the fitting for that job, and the Crouse-Hinds CPR2 is one. Thread couplings require you to rotate one length of conduit into the fitting, which you cannot do mid-run when both ends are strapped or buried. Compression clamps onto the plain conduit ends instead, so you can cut out a damaged section, slip the coupling on, and tighten. Rigid or IMC, ordinary locations.
5) Can I use this coupling in a hazardous or classified area like a fuel room or spray booth?
No. The CPR2 compression coupling is classified for ordinary and non-hazardous locations. A Class I or Class II area needs an explosionproof fitting rated for that division, and a compression coupling is not a substitute for one. For unclassified commercial and industrial work, concrete pours, and underground distribution, it is the right fitting.
6) Is the Crouse-Hinds CPR2 coupling NEC compliant, and does it work for Canadian jobs?
The CPR2 compression coupling is built to NEC/CEC standards, so it covers both the US National Electrical Code and the Canadian Electrical Code. For a spec-driven institutional or government project, that is the standards reference on the fitting. What you still have to match to your drawing separately is the area classification: this is an ordinary and non-hazardous location fitting.
7) Do I have enough room for a Crouse-Hinds compression coupling in a tight ceiling or congested wall?
The CPR2 compression coupling measures 5.2 inches long by 5.6 by 5.6. That is a bigger envelope than a plain threaded coupling because compression fittings carry the clamping hardware on the outside of the body, so check your clearance before you commit, especially in a stacked conduit rack or against a deck. Where you have less than that, you want a threaded coupling or a union instead.
8) How do I order the right Crouse-Hinds compression coupling for 2 inch rigid conduit?
For 2 inch rigid or IMC, the part is CPR26. There is nothing else to specify: the CPR2 family varies on trade size only, so once you have the size you have the part number. Just confirm you are working in ordinary, non-hazardous locations and that the run is rigid or IMC rather than EMT, since this coupling is not an EMT fitting.
9) Why is malleable iron used on a compression coupling instead of steel or zinc die cast?
Malleable iron takes the clamping load of a compression connection without cracking, which is the failure mode that matters when a coupling gets torqued down hard on a large conduit or gets struck during a pour. The CPR2 body is malleable iron throughout. It is also why the fitting has real mass to it, a single unit runs 3.2 pounds, so on a large fitting count budget the weight into your material handling.
