RMC 90's not 90

[electrofelon]

Anyone else notice this? They always seem to be a little less than 90. Super annoyed.

Ya know, I didn't complain the last few times this happened......But I paid for a 90, I want all my degrees!

Ask for a pro-rated credit.

Also gotta love it when the ends of all yor EMT 90s are egged on the ends.

 

[Dsg319]

And make sure when making measurements,install it with the same end that you measured it. Lol

 

[electrofelon]

Seriously tho most of them seem to be quite a bit shy of 90. I have noticed this in the past. This one I got from a supply house. I just went to big orange and looked at all 10 they had. 8 were all the same 76 degrees or whatever just like the one from the supply house. Only two were real close, one being a hair over and the other a hair under.

Last time I used RMC 90s was about a month ago and I don't remember them being really off

I've noticed it with PVC 90s for sure.

Maybe they send all the bad ones to Seattle

76??? Could you have meant 86?

That’s quite a bit off from a 90. If it’s going to be seen I don’t know how you could use it.

 

[electrofelon]

Yes, and I was a math major in college, got a 3.74 GPA . Hey it's been a real long day...

 

[electrofelon]

Yes I meant 86 degrees. That's just a guess. It is quite a bit off, well out of the range of acceptable. I'll try taking a picture when I'm back there tomorrow.

Huh? What are you talking about?

Rigid metal conduit factory 90's being significantly shy of 90 degrees and making your installation look like crap so you have to go out and track down a 90 that isn't junk race to the bottom imported crap.

I installed a 2 1/2 " mallable LT, one end was not threaded straight, had to install, not able to get replacement. It was along side a panel, very noticeable.

I was back at the house today where I used the 90s a little while back. Sure enough, I didn't even notice but the one going above the roof line is not 90° - It was so hot that day I just wanted to get gone

I guess we should start calling them 88s

It is an issue with RMC 90° elbows. A while ago I ran some 3" RMC for a fire pump disconnect and I couldn't get the horizontal pipe level and the vertical pipe plumb. Was off about 2°. Had to cheat the horizontal to make it look decent. Sometimes if you back off a 1/4 turn in the couplings you can fudge it with the slop in the couplings.

Wow. I thought it sucked that PVC 90's were alway off a few degrees. Now that crappy standard has fallen upon RMC? So what do we do, turn into iron workers and heat one side of the bend with a torch and cool the other side with rags and ice water?? That does work, but I don't think we should have to change trades because of crappy manufacturing.
