Sch 40 we use medium body / medium set
sch 80 we use heavy body / slow set gray. Need a little extra time to get the cement on on large sizes. Also, it helps tremendously to block off the open ends if you have any on large diameter stuff. Keeps the breeze from coming down the pipe and drying the cement before you get it together.
If it's going into service quickly or if it's really cold outside I use medium body / fast set
All made by oatey.
On a side not, Duct tape placed 1/4" from where hub will end up makes purple primer look downright pretty when you peel it off. Plus there's no doubt if the fitting is bottomed out on the pipe.

We use Hercules clear medium body glue. If it were up to me I wouldn't use it. You get occasional leaks in it no matter how careful you are. One time we roughed a two story three bath house and had about half of the joints leak. Their is no way we are just that bad at using PVC, their had to be a bad bath or something.
I noticed their are usually a lot of air bubbles in the glue. This batch had even more then normal, maybe that's what did it.

1 1/2" = 3/4"
2" = 7/8"
3" = 1 1/2"
4" = 2"
That what you use for where the hub will end up?

If we are splitting hairs I think 3" is 1 9/16" and 4" is 1 7/8". I'd have to measure the hubs. It's been a while since I ran PVC.
I think 2" is 11/16"
According to the Charlotte plastics dimensional catalog it's 7/8".
I will!
I was taught that it is 7/8". But some time ago I noticed it wasn't that anymore. Cut a 1 3/4" piece of 2" pipe and glue two fittings together with it. There will be a 1/8" gap every time. I am almost positive it didn't use to be that way.

Shoot man! I been usin Elmers all these years:laughing:
What brand fitting are you using?
Charlotte fittings stay pretty true to the catalog specs, others, notsomuch.
Mueller and Lasco are notorious for under spec fitting hubs, Nibco is in and out, but the ASTM specs for the hub is 7/8".
Recently it's been a lot of Mueller and a bit of Nibco. HD Supply carries Charlotte Pipe fittings but lately they have been crazy expensive. I can go to Lowes and buy Charlotte Pipe fittings for about 60% of HD's price lately. I don't do that so I turned to a different source. Never made the connection to the out of spec fittings. Now I need to evaluate my buying practices for PVC fittings. Hmmm...
Hey, thanks man! I not only learned something new, my original understanding of what it was supposed to be was validated.
