Hey guys, I have a 68/4500 valken graffiti tank with a crossfire regulator. Today I noticed my tank was leaking from the fill nipple opening, not the threads. I emptied it, took out the nipple replaced the tiny oring on that piston and re-tefloned the threads and screwed it back in. The leak was alot smaller now but still defientely coming from the fill nipple opening. Saw they sell them for 10 bucks on ansgear, should I just go ahead and order a new fill nipple and replace it or could it be the regulator itself?
Is it a stealth system reg or one of the older ones? It is probably best to clean and relube the reg internals. You may have received dirty fill(s) and it it the debris and find dust that could be causing the leaky fill nipple.
Also, what kind of material was your replacement o-ring made of? Regular buna (the standard black stuff) doesn't hold up well when used in a spot such as the fill nipple. The filling process is pretty harsh on that o-rimg so a harder material is better suited for the job.
