Hi Mark,
Have you measured the ID of the wagon wheels, in comparison with the ID of the center body opening?
The ID of the wagon wheel and the ID of the exhalation side of the body are identical.
Something else I had never noticed with the Hope-Page. The wagon wheels are specific to inhalation and exhalation sides.
This can be seen in two ways.
First, there are small round mold marks on the wagon wheels; however, they are on different sides on the two wagon wheels (ridge and non-ridge) so that the valve can lay flat on a smooth surface (the opposite side of where the round mold marks are).
Second, the hole in the middle of the wagon wheel is recessed on the mold-mark side of each. Again, to accommodate the valve itself laying flat on the opposite side.
Hope I'm making sense and that this isn't something everyone already knew.
Bottom line is that using the correct wheel on the correct side with the correct orientation is important. My 2psi. Mark
