Leak rate of 3.0 gph at 10 psi* with PD = 100% and PFA = 0%.
Leak rate of 0.2 gph at operating pressure with PD = 100% and PFA = 0%.
Leak rate of 0.1 gph at 1.5 times operating pressure* with PD = 100% and PFA
rate varies as a function of pressure, this leak rate and pressure were
certified using an equivalent leak rate and pressure, in accordance with an
