Threading and Oring gland help
Orings
For standard -0xx orings in dynamic applications what is considered a generally acceptable gland spec? Yes, I know they vary by circumstance, but what is considered about average?
Stretch % -
Squeeze % -
Extrusion Gap -
Break edge radius (top) -
Bottom edge radius -
Gland fill % or gland width (I built a calculator that derives gland width from the desire fill %) -
Threading
I don't know why I am struggling with this so much... When I used to do machine design we always bought these components and since we had an in-house machine shop, we just specified the thread (they determined class, etc). I need a super shallow pitch... something similar to the DM bolt can or the MacDev valve can. I have limited depth so I was thinking a custom ACME thread would work, but I don't know if most machine shops could make it?
