1> everything but the PVC parts may be rated for high pressure, but PVC is NOT rated for gas.
2> universal gas laws -- pressure is exerted on all surfaces equally. Thus your PVC parts are seeing the same pressure as all other items regardless of their pressure ratings.
3> T-Shirt cannons are, by design, to be near the public (within shooting distance). Knowingly using non-gas rated parts in a gas (air) cannon may be gross negligence should something happen (I'm not a lawyer but this seems a reasonable argument).
All I'm saying is in this lawsuit culture, you may want to consider overdesigning a bit for safety.
