x valve parts kit and ULT parts question

[foodboy]

Hi

So if I'm buying back up O rings and stuff for my x valve with ULT
does the rt parts kit have everything I need?
What about the ULT O rings are they the same as the regular on/off O rings?

Could some one give me recomendations on putting together commonly needed back up
parts for my x valve with ULT?

Thanks
