If the main valve is leaking, Jim will replace them. Make sure you ask for a replacment of the same "flow" type. He has several different flowing valves, and you'll want to match your older flow type with the new one. If you get a higher flowing valve, then you will get too much nitrous and possibly have a lean condition. If he gets lazy, and says that you'll need to adjust your nitrous to the new valve, then you can be assured that you are NOT getting the same flowing valve.

That brings us to the BOSS regulator. It regulates only bottle pressure, not flow.

 

Thanks for the info.i was going to just get some good orings the nitrile orings they are using are not rated for the blow off presures.they should be buna for the presure ratings we reach.

 

Valve O rings do go bad. But I've never seen a new O Ring blow before a blow off valve does. But im sure there are stranger things that have happened. Are you sure the leaking is coming from the O-Ring and not the valve? Most of the time the big problem with Jim's O Rings is that they swell up once exposed to Nitrous and when you remove the valve you have to wait abount an hour to get them back on! LOL

 

All three leak from the thread area i made a fast asumption that that would be the oring but might look closer i would think if it were the valve it would leak around the **** stem????? is this a good asumption or should i rethink it.[img]i/expressions/face-icon-small-confused.gif[/img]

 

Soap and water will find that out right now. I think it more likey around the valve than around the base itself.
