Why would it matter on a pipe schedule system? You'll just have way more water than you need. I don't recall pipe schedule in any hazard being restricted to less than an 8.0 K (nom.) but I could be wrong. Tyco and Viking have the 8.0 with a 1/2 NPT (listed for retrofit only) where your reverse situation applies.
