There are two types of Pex - A and B. Can't remember which is which, but my understanding is that fittings for one of them don't effectively reduce the size of the tubing. However, the other one effectively reduces the tubing by one size. In other words, that kind of 3/4" fitting has roughly the interior diameter of a copper 1/2" fitting.
But it sounds like you may have other problems than that one fitting.

Pex A is the one that is flexible and uses the milwaukee expander tool to connect the fittings. This is less restrictive to flow
Pex B is the typical pex that uses brass or metal bands to connect the fittings. Crimp or clamp fittings for pex B

Pex is 1/8 smaller ID then the pipe you're using.1/2 pipe is 3/8
If you are using uponor/ expandable pex the ID is a true size 3/4 is 3/4
If you are using uponor/ expandable pex the ID is a true size 3/4 is 3/4
