Is the AC low side port removable?

[gmdrvr]

The schrader valve in the low side port is broken in a way where I can't get the valve out. I went to the store and picked up a low side service port and figured I would get the high side to while I was there. I replaced the high side port no problem but the low side doesn't seem to unscrew, does GM soldered on the low side or something?

only the core is replaceable on tat fitting or your replace the entire hos assembly.
