This can be frustrating but you need to read <R66>:

<R66> In addition to the items included in the KOP, pneumatic system items specifically permitted on 2011 FRC ROBOTS include the following items. All included items must be “off the shelf” COTS pneumatic devices rated by their manufacturers for working pressure of at least 125psi and burst pressure of 250psi, and used in their original, unaltered condition (except as required for assembly with other components).

The 92C was supplied in the KOP therefore it is legal regardless of the manufacturer's specifications. The 90C is being provided by you and you must provide documentation that it has a rated working pressure of at least 125 PSI.
