Would a valve with 1/4" push-to-connect ports be legal? (1/4" push-to-connect fittings work with the KOP-supplied 1/4" tubing.)
...or would we have to purchase valves with 1/8" NPT ports and then add 1/8" NPT to 1/4" push-to-connect fittings to be legal?
An installation would be a lot cleaner if the valves already had 1/4" push-to-connect ports since those interface directly with the required tubing.

The 1/4" push-to-connect fittings is a different thing from the 1/8" port size. The 1/4" push-to-connect fitting is how you are actually going to connect to the valve or manifold. The 1/8" port size describes the size port that the fitting fits into. To be frank, this isn't clearly laid out anywhere that I've found, this is simply my understanding of the valves after working with them for many years.
