Yup, that's what I was getting at Chuck. The style manifold that you have doesn't generate a negative pressure to suck the air out of the seal. Instead the air evacuates under the seal pressure blowing out to ambient. In the new style HWH manifold, the one that I have, there's an air driven PIAB vacuum pump (no moving parts) that creates a negative pressure less than ambient to actually draw the air out of the seal. It's neat to see work. When the air is truly sucked out of the seal the seal tucks itself way into the retaining channel creating a ton of clearance for the side body to move.
