How do I fix my nipple?

[dyerules]

I just got my new X-Stream the other day. I heard the fulll nipples on them go pretty fast so i figure why not fix the problem before it happens. I'm gonna order a new one to put on but I'm not sure if i need a certain one for 4500psi tanks or if i need to put an o-ring in it and stuff. So if you guys could help me w/ this info I'd appreciate it. Thanks

well from what i know i am pretty sure that all fill nipples are rated the same.
if u ordered a new one it should come with the hole assembly. just make sure the tank is empty. screw the old one offf and screw the new one on. make sure to use teflon tape as u dont want it leaking at all.

i also think that it don't matter what size tank u got..i think all the fill nipples are universal but i may be wrong never had to replace one
