Anyone ever install 4" EMT with intergral COMPRESSION coupling? Thoughts on pro's and con's. Thank you.

Actually Infinity replied back in 2012 to my similiar post...."Yes it has either a compression or set screw coupling integral to the EMT. Works very well in riser situations. If lots of bends are involved I've seen a big pile of cut off couplings on the floor. :roll:"
Why would there be a lot of cut off couplings if many bends?

Because the apprentice running the bender was still learning.
The bent piece needed to terminate via a connector.

I'm not following how having a lot of bends would cause having to cut off a lot of the intergral couplings?
What if you have a bend in the middle of a 10' stick of EMT? That would not affect the coupling?

You have never had to shorten a piece of pipe because you bent it wrong?
Each piece of conduit will need a coupling or connector at the end. If you bend the pipe with the intent of installing a connector to enter a cabinet but your bend is too short you either re-bend or add a coupling and short piece of conduit as needed.

Sorry i'm still not following how having a lot of bends makes using EMT with integral coupling less useful as you may wind up cutting many coupling off as Infinity stated.

I got to ask. Intergral couplings?? Is this emt with a coupling welded on one end or something how’s its intergral

Kwik-Fit® Compression EMT
Kwik-Fit Compression EMT has all the benefits of E-Z Pull EMT with integrated couplings. These built-in couplings significantly reduce installation time, and eliminate the need to purchase, inventory, and install separate couplings.

Do those really save time… you have to tighten one end anyway. And look at all the cut ends you can possibly have with a bad bend. Just curious.

That's what ZI'm not following....possibly having many cut ends because of bends.

Anyone else have opinion on using this over having to install the couplings?

If the run is straight for a good distance you just strap up the conduit and it doesn't matter where the integral connectors end up (or it's easy to measure and cut to make them end up in a good place). If there are bends, and the bend is put too far from the end with the connector that needs to fit to an already installed piece, but the bend you just spent a bunch of time on is otherwise good, then the connector gets cut off to adjust the length of the pipe. Many of us have a strategy of erring on making the distance to the bend to long instead of too short, because if too long you just cut it. Doesn't work well if you wanted to put an integral connector there. The integral connector probably isn't worth the money if you have to remove the already strapped up piece your fitting to, in order to cut it.

Imagine working with PVC conduit. It can require cunning to use every belled end.

You mean coupling, correct? Thanks

Picture EMT without any factory couplings. You bend a piece and it's 4" short so you put an extra coupling in along with a scrap piece to make up the difference. Since your only 4" short you will probably have to cut off your pipe because there may not be room for a 4 " coupling and a short piece.
Same job with factory installed couplings and you make a bend, and it is off you will have to install a field installed coupling you may have to cut off the factory installed coupling and waste it.

Got it 100%. How often are bend made short? If the bend is off with factory installed coupling and it's short by 12" or more( or there abouts) the field installed coupling is fine to remain on?

It depends on which way you're running it, coupling first or last, as to which is more lay-out-efficient.
Also, standard EMT can be turned around if one leg of a bend is better suited to point the other way.

So you think it's a time saver to use the integral.coupling?

You wouldn't have carry around a box of couplings.
