Pressure Outside DWV

In a coaxial for example, would it be safe to use a DWV coupling on the barrel as a sealing face? This way I would'nt have to worry about cutting a smooth surface. i'll probably just get a PW one but I was just wondering.

DWV is wrong in your title...
Your question can be simply answered with yet another question. Will this part being experiencing any amount of force for any amount of time?

Obviously because the sealing face will be pressing against it. I don't think it's gonna make a difference because the DWV is the same type of PVC, not any lighter or anything, all that's different is the bonding aread, which plays no part in this.
The barrel experiences force, so I don't know why a coupling shouldn't be able to hold up.

Ok thanks, since I can't cut smooth surfaces myself I'll probably have to add a coupler. Would I need to glue it on? I'm guessing yes.

If it's DWV PVC it's probably fine... The company's just say DWV just to cover their butts because it COULD cause shrapnel... but a couplins blowing out most likely wouldn't do any damage if it somehow did break...
If it's DWV ABS it's 100% fine in a Combustion... I'm not sure about a Pneumatic ABS though...
for "glueing" ABS use ABS Cement
for "glueing" PVC use Primer first (normally purple) then wait about 30 seconds for the pipe to "melt" (you can't see it "melt") and then use PVC glue
If you must resort to All Purpose Cement make sure it's for ABS, PVC, and CPVC (All Purpose isn't as good in my opinion)
"glueing" pipes is called Solvent Welding because the pipes get bonded together as if you welded them

No more drunken ramblings please...
