I got back an interesting reply.
Thank you for your order.
In the notes of your order, you asked if the PVC fittings you were
ordering were rated at-least at 150 PSI.
They are, but only for liquid, not solids or gas.
Will these work for your application?
Since we are unsure if these are what you need, we will be holding
your order aside until we hear back from you with how you would like
to proceed with your order.
Only for liquids?
I always thought PSI ratings were that, no matter what was exerting the force (Gas, Liquid same PSI).
BTW: How does solids have a PSI?
