How can a filter test at 99% @ 20μ when there's oil bypassing the media?
Oh no I meant sitting loose in the center tube.
Can't see whats stopping some oil from flowing by the soft pliable lip of the ADBV.
In these attached photos of some differently designed filters you can see that the ADBV fits around a metal rise or lip which is part of the end cap and will not collapse or flex. The silicone or rubber lip of the fram ADBV has nothing to support it from flexing and will surely allow some used dirty oil to remain unfiltered as it flows by and joins the stream of returning oil.
You do realize that the whole area between the two red circles seals up against the metal end cap. In fact, the Fram ADBV has way more sealing area than any of those other filters you posted. So I really don't think you're grasping how the ADBV seals. It's clamped between the end cap and base plate, and seals on both sides, just like any other ADBV does. There's a possible oil leakage path on every ADBV in every oil filter make of the sealing area isn't 100%.
Oh you got me, I had no true understanding of how a filter(especially an ADBV) worked but now that Ive seen your circles it's as if scales have fallen from my eyes. I see so clearly now. All hail the circles!
Anyway apparently somebody got butt hurt about something I said about fram and reported to a moderater. So Im not gonna carry on this conversation.
