Does anyone know:

What happens if you try to use the standard Ridgid HS or alloy 12R dies to thread PVC? I assume the pitch and taper of the PVC thread is the same as galv or brass, what goes wrong with threading the PVC pipe?

Re: threading pvc pipe

I use my standard 12-r dies to thread pvc, I do it infrequently enough that I'm not buying a special die head for it. Seems to work just fine.

Re: threading pvc pipe

I also just use my standard dies when I need to thread PVC. I do that about once a month and never have any problems with it.

Usually all I thread is 3/4" schedule 80 PVC. It goes so easy I can just turn the die by hand to thread it.

Re: threading pvc pipe

Threading PVC pipe is used for mechanically joining two sections of the plastic tubing. This process is used for containing the high pressure..

Re: threading pvc pipe

The temperature of using is not too high for the pvc pipe, othewise, it will be deformation.

Re: threading pvc pipe

Wouldn't it be faster to just use a 2" x close sch 40 brass nipple? I guess if you do a bunch of urinals you could premake the pvc nipples.

BTW: For the first time on Friday I saw a urinal auger in a catalog. I bought it. I'm perfectly willing to wait to use it though.

Hey Geno can you post a picture or link to the Urinal Auger when you have a moment please............!!!!

Would love to have small hose that we could use to get around urinal traps without having to take them off the wall. Bill's small hose is just too long on the head

It will work, but the problem is that it can tear the pipe if you are using a machine Like the 300 or larger. I have ran miles of SCH. 80 for D.I. Water. Even with the plastic recommended dies it will tear the threads some times. I found that if you are using a threader with a carriage, then help the dies along a little bit. You can also start the machine with the die not engaged over a little bit of the pipe, start the machine rotating, then slowly engage the die. Always have more pipe than you need when threading PVC.
