I noticed what the issue must be. The two o-rings actually had a different material. I compared a handful of o-rings I had and the FKM material is somewhat set in place, that is the shape tends to have no memory while the nitrile o-rings love to return to their O shape.

Actually the...
On page 98 of the Parker Handbook, section 4-18, there are listed cross sections for o-rings and groove dimensions.
The smallest cross section listed is 1.78mm, the handbook doesn't list any smaller.
I tried 1.78mm and made and tested a working seal. I wanted to decrease the wall thickness of...
Thanks Tugboat,
So fundamentally I need to find the force requirement for the material and find some fastener configuration that distributes the forces over the length of the o-ring correctly.

How much does it matter where the fasteners are placed on an o-ring face seal?
Park O Ring handbook doesn't say anything about it. I'm currently using a racetrack groove. I've made the radius of the groove curvature 3x the diameter of the o-ring but I worry about where I've placed the screw...
Quite often I see plastic enclosures with light indicators that I assume are waterproof but are not removable or fitted, rather bonded to the surrounding plastic.
Looking at the indicator you can see that it's often a light pipe. How exactly is this achieved, is it overmolding and are there any...
