Hi Guys
I am replacing a shaft seal set on a Stal comp with a 75 hp Storch motor running on NH3.
In the shaft seal set I have two O rings the same size ( only one required) One of the O rings is marked "FPM".
I believe that this "FPM" indicated the type of refrigerant that it is sutibale for - though I am not 100% certain.
Can anyone give guidance as to which one to use on NH3.
Thanks.
