The shut off device that is triggered when the
propane is turned on too fast or a large leak occurs is NOT in the regulator
It's in the newer flexible lines what have the Acme thread and large knob
In this link in the 8th or 9th paragraph down it states:
Propane 101-The basics
This is significant because two safety features are built into the Acme nut itself. First, Acme nuts contain a thermal bushing, which will melt in a fire, and prevent the escape of gasses from the tank. When it melts, it allows the new OPD spring activated shut off valve, which will only allow the flow of gas if a fitting is attached, to pop out and completely shut the flow down. They also have an improved excess flow check valve, compared to the valve in the old POL fitting-more on that later. The new Acme nut also adds an O-ring to further help prevent leaks at the connection.
