Why doesn't the center pin on the hoses stick out far enough to push in the shraeder valve? Am I doing something wrong or is this just junk?

Turn the pin counterclockwise to extend.

Are you sure it is 1/2 not red(1/4" sae), yellow(1/4" sae) and blue(1/4" sae) charging hoses?

You Are Correct.; These hoses are equipped with 1/2”-20 UNF (5/16”SAE) connection with core depressor on the unit side and 1/4” SAE flare on the manifold side. Hope This Helps.
