Crouse-Hinds ECGJH212 – Frequently Asked Questions

1) What hub sizes and lengths does the Crouse-Hinds ECGJH flexible coupling come in?
The EC Series forged brass flexible coupling runs from 1/2 inch through 4 inch hub, with flex lengths of 4, 6, 8, 10, 12, 15 and 18 inches depending on size. The 1/2 inch and 3/4 inch hubs have the fullest range (4 through 18 inches). The 1 inch hub covers 6, 8, 10, 12 and 15 inches. From 1-1/4 inch up through 4 inch the choice narrows to 12 and 15 inch lengths, with 1-1/4 inch offered at 12 inches only. So if you need a short 4 inch jumper, you are in 1/2 or 3/4 inch trade size.
2) Can I use this coupling in a Class I Division 1 area, or is it Division 2 only?
Class I, Division 1 is the rating on the Crouse-Hinds EC Series brass flexible coupling, which is the more demanding of the two, so it is acceptable in Division 1 and Division 2 areas alike. Division 1 means flammable gases or vapors can be present during normal operation, not just under fault conditions. It is built to NEC and CEC standards.
3) Does this coupling thread into a conduit body, or do I need extra fittings?
Both ends are male, so the EC Series coupling threads directly into female-threaded hubs, such as the hubs on an explosionproof enclosure, motor terminal box, or conduit body. If you are tying into a run of rigid conduit that also ends male, you will need a coupling at that end to convert.
4) Why use a flexible coupling instead of rigid conduit into a motor in a hazardous area?
Rigid conduit transmits vibration and leaves no room for the small misalignment you get between a conduit run and a motor or pump terminal box. A flexible coupling absorbs that movement while keeping the explosionproof containment intact, which is the whole point of the EC Series in Class I, Division 1 areas. Typical uses are motor and vibrating equipment terminations in petrochemical, oil and gas, chemical, paint, grain handling and pharmaceutical plants.
5) Which Crouse-Hinds part number do I order for a 3/4 inch, 12 inch long explosionproof flex?
That is ECGJH212. The numbering follows a pattern: ECGJH2 is the 3/4 inch hub and the trailing digits are the flex length, so ECGJH26 is 3/4 inch by 6 inches and ECGJH218 is 3/4 inch by 18 inches. For 1/2 inch hub the prefix is ECGJH1 (ECGJH112 is 1/2 inch by 12 inches).
6) What size hub do I need if I am running 2 inch rigid conduit to a piece of equipment?
Match the hub to the conduit trade size, so 2 inch conduit takes the 2 inch hub coupling, ECGJH612 at 12 inches or ECGJH615 at 15 inches. Larger runs are covered too: 2-1/2 inch (ECGJH712/715), 3 inch (ECGJH812/815) and 4 inch (ECGJH1012/1015). Above 1 inch trade size, 12 and 15 inches are the flex lengths offered.
7) Is the brass body a problem in a corrosive or wash-down plant environment?
Forged brass is the construction on these EC Series couplings and it holds up to corrosion better than plain steel, which is why it gets specified in chemical and petrochemical service. Brass is also the usual pick where a non-sparking material is wanted around flammable atmospheres.
