O-Ring Design

[SlartyBartFast]

Anybody know of good reference material that discusses designing pistons, shafts, and what o-rings to use?

Something that would discuss how to space feed ports and o-rings for a 3-way valve type arrangement.

From what I understand, Tom can talk for hours about o rings.

Well, if Tom would like to talk I'll foot the telephone bill.

But really, what I need is bore size and shaft size tolerances required for different o-rings and the pressures that they could withstand.

BradAGD made me aware of this company a while back. they are located here in Houston (good for me, probably useless for you! ). they have a technical section on o-ring loading and deformation, etc...
make sure to explore all of the "sections" under the sub headings on the left. it at first looks like there isnt much info there, but look around, theres more pages to explore for each area.

this isnt exactly what you had asked about, but i think its good info to have available..

hope this helps!
