This is the way it should work, and has worked for everyone else. I lubed everything - Diver, O-rings, caps, everything, just to see if it would come together. It should work just like the Scuba, which slides right in without any lubing of O-rings.
So the tool should completely pass through the caps, correct? Mine does not at all.
Excellent that my experience is the exception, I love love love the form factor and fill concept of the SnP and really want it to work.
