Ok I think I got this figured out.  I was trying to use the old o ring on the actuator side of the valve. The new one I ordered looked a lot thinner and smaller diameter than the old one. I thought I was sent the wrong o ring. The old one looked good so I tryed to reuse it.
Is it normal for orings to swell up after a while?  I tryed the new oring and everything slid together easy.
