what is this fitting?

[electrofelon]

I assume it is some sort of clamp coupling, but I have never seen one before. I dont know if the raceway is rigid or EMT.

It is very similar to the splices we see on Air Systems for moving grain.

I've seen it used on plastic moving systems

 

[nickelec]

I have seen plumbers use something very similar with a peice of rubber inside to temporarily stop leaks

So we are thinking this is a non electrical fitting that was cobbed in? Note there seems to be a gasket between the raceway and this fitting.

There is a similar electrical product called a "split coupling". Here is a CrouseHinds sample.
That may be one of a different manufacturer.

Ahhh, there it is! So what is that for? For when you pull the wire in but then realize you forgot a coupling?

I installed what seemed like a thousand of those in a plastic resin conveying system that I built from scratch for one of our plants. Started commissioning the system on a Monday and got told on Wednesday that the entire system was going to be moved to another plant.

That fitting probably has a stainless steel sleeve inside a rubber sleeve covered by the visible steel. Definitely not code compliant or listed but a hell of a solid connection.

And probably does not establish a solid electrical connection if the raceway is expected to serve as an EGC.

I doubt it is rated for wet location. Seems to be UL listed and listed for concrete as well as Class 1 Division 2. It is made to join rmc to rmc

Split Couplings:

• Provide a quick and easy method of joining two pieces of threaded rigid or IMC conduit

Rigid Combination Couplings are used:

• To join rigid conduit to EMT or flexible metallic conduit

Maybe repairing EMT that has been smacked with a forklift and cracked/split the original fitting so that it wont tighten up properly again. Lot quicker than tearing apart the entire run to do it correctly.

What is shown in the OP is a "low pressure repair clamp", (not listed for electrical AFAIK) not a split conduit coupling as shown by Gus and linked to by Dennis.

As far as I know there is no wet location listing for a rigid conduit coupling of any type.

I agree.

For mid-run repairs, or if there is no room to spin on a 90 or an offset.
