Nope -- It's me who is wrong. Quest and Vanguard polybutylene piping is in fact copper tube size.
Sure, because all three of the piping materials you mention above are copper tube size. Quest and Vanguard polybutylene piping, otoh, have a different outside diameter.
Qwest tubing isn't CT (copper tube) size. SharkBite fittings won't work on it.
