Justin, Great Vid., your reg is a Firepower reg, which is really a Victor import. It is identical to the Victor SR5B. The kit you bought wasn't the exact kit you need, but the seat assembly for the SR250 and the SR5B are identical. Now you have a diaphragm that will bounce around on your bench for a few years. Finally you'll throw it away, and one of your friends will need it the next day. I have parts like that laying all over the place. This is a shameless product placement, but I have the kits for most popular regs on eBay. Check out our store if you need any other kits. You'll save a few bucks and we include Krytox grease to assist in a perfect rebuilt. I'm starting to see a need for repair tutorials for gas apparatus. anyway, thanks for sharing. Oh, quick tip. You can put the inlet stem in the vise perpendicular to the rotation of the cap, and then use a pin spanner wrench to remove the cap without marring it.

I have a question on the part you fix to set the pressure can you decrease the pressure the same as you do to put the pressure on gauge or you can't decrease?

Ouch!! Vicegrips on brass?? ...why? Edit: you can omit the bottom pair of vicegrips by screwing the regulator securely to the bottle with face pointing up and service the whole thing like that and tape up the jaws of your vice grips or use an automotive wrench (aka F wrench) or a plumber's spud wrench or some smooth jawed channel locks. Just saying, from craftsman to craftsman, gummed up brass is the sign of a hack posing as a craftsman. ..its like those "handyman" types who have a bucket of tools painted a bunch of different company colors. Here's a tip. Next time you see a used bicycle inner tube, cut it up into long strips along its seam lines. Roll them up and use them for shit like wrapping your regulator so you can grip it in your vicegrips without marring it. Its also useful for tying up cords, wrap hammer handle, blah, blah, blah...

This is an excellent training video, of what not to do.

My Victor regulator doesn't look anything like this one on the inside.

saludos, tengo un regulador igual al de el video. y tengo una duda cuando le abro la valbula al cilindro se escapa algo de aire por los 2 orificios que tiene en la tapa que se desenrosca para abrir el manometro y si le tapo esos 2 orificios entonces vota aire por el tornillo que es con el que se regula la salida de bar. no se si me explique bien pero la pregunta seria tambien si esos 2 orificios son para que salga aire? o estara mala la menbrana gracias de antemano

you have more rings than my wife

Mine is leaking on that little hole on the top,

I strongly suggest studying the factory manuals (you can download most of them) and if doing oxygen regulators learning to clean to oxygen safe standards.

Can a regulator suddenly stop working at all not due to mishandling or damage ?
