Heard you have to get it re-hydroed and all that jazz. I don't have to worry about bottles being out of date so I really don't need it hydroed if I don't have to.. Bathtub work?

Can't I just buy a valve and unscew the old one and then scew in the new one and be done or is there some parts or tricks I need to do for it not to leak.

This would be on a NX 15lb bottle by the way... I have 2 bottles I would like to change over to the new style valve.


Thanks...

 

Just unscrew the old one and screw in the new one.
