Thank you for the reply. I had read that and was hung up on the meaning of "functionally equivalent." I was wondering if the "functionally equivalent" applied to the "function of the part - as tubing" or as "function of the part - regarding performance." 3/8 will deliver more than twice the flow volume of 1/8, which would have been a real advantage in speed of cylinder deployment.

Thanks for the help in interpreting the rule!
