Shower valve replacement

I'm replacing my shower valve finally. There's copper behind the wall but I'm just going to sharkbite that to plastic to make the replacement go smoother/easier.

The type of fittings I bought to screw onto the valve are female brass to 1/2" pvc. If I'm using dope on those threads, is there any problem with "really cranking" them tight? I just put the valve in a vice and tightened them with a 12" crescent wrench until I was satisfied. Is there such a thing as over-tightening when it comes to that?

Yes you can over tighten and crack the valve body. Since the fittings are tapered and the body is a soft mental it can happen. ( Has happened to me )

I used pro dope from home depot. I've had it for years but never liked it too much due to the mess.
As the nit pick that I am, I redid it with tape. Seemed smoother, I guess tape on tapered thread is a good plan.

Thanks!
