Chamfer Mounted O-Ring

Chamfer Mounted O-Ring

Chamfer Mounted O-Ring

(OP)
I am in the process of designing some air driven pile driving equipment.

For many years, the company I worked for/was principal in designed and built pile hammers with a Corliss style valve.  In the late 1960's we added a valve liner with an o-ring mounted in the corner of the liner.  A chamfer was cut in the cylinder and the o-ring was mounted in the chamfer.  You can see how this worked at

At one time we had a chart which gave recommended chamfer dimensions for o-rings mounted in this fashion.  This has dissappeared along with many other things.  Now I'm working on a valve/valve liner of a different size, would love to have such a chart.

It's not the best way to mount an o-ring, but the pressures are low (< 150 psi) and it's worked well for forty years now.  Anyone familiar with this type of mounting?  Or a chamfer size chart?

P.S. Don't be thrown by the "Geotechnical," my BS is in ME and it's necessary for someone to intelligently design pile driving equipment to be familiar with its application.

Thanks.
