SCBA Tank Valve Fitting Size (NxG2)??

You COULD just replace the whole Scott valve assembly with an original, unmodified Scott valve. I can get them for $15 (my cost) & ship one out to you if you decide to go that route. PM me if that's what you decide . If you've any other tank questions feel free to ask me. Been working with them for 25 years. Gerry
Do you have that same 4500 psi snap change valve for sale? If yes what is the best price shipping to FL?

Also, how difficult is to exchange the original valve to a snap change valve? The tank will still hold pressure?

Appreciate your comment on this matter.
