rubber. We modeled the parts in solidworks and then estimated space required. We ended up facing the die about 20 thou to get the compression just right. The V was a standard 90 degree cutter.

Thank you for posting this discussion and sharing the pictures of the process!

What durometer did you end up using on the O-ring material? Did you try other durometers to end up with your final choice?

We ordered some soft A50 and medium A70. We used the A50 because it was easier to work and appeared about right.
