How does a stepped split section work? I can't quite visualise it.
Wandering off topic now but I wonder how feasible it would be to convert, say, a HW95 to a PB ring seal?
Instead of having a straight cut in the side of the ring, the cut would be something like this, making it more difficult for the air to leak past the two ends of the ring
