I'd be more concerned about the diaphragm at higher pressures that the casing.


The bolts are in tension Jack... :wink:

@ LL... what's it rated for? Without the means to test it, safe money says....stick with the rating.

Or take yer chances.

Sorry jsr, no info on the bolts, I can open it up and get some pictures though. Also, how would I go about supporting the diaphragm for use at much higher pressures?
@ gippeto:
I don't think pressure rating says much about qevs; most of the QEVs used on this site are rated to 125 psi maximum, but they are regularly used at much higher pressures than that.
