He has them on the shelf. They come with a standard LPI nipple on the input side. I don't know if it's got a filter, didn't ask and haven't disassembled mine.

OP
I spent the day with him yesterday, there's no filter.
OP
I'd be interested in better understanding your want to change the nipple? All I can come up with is either you want a higher flow or you don't like the restriction a nipple may place in the flow path, but just guesses here. What are you moving to, a QC6 type connection or direct hose attachment?
And are you pro-filter and why?
OP
Neither, not concerned about flow rates at all. Basically I don't need to disconnect the MAV/needle from the reg, and having it come undone in the water is bad. Direct connection of an LP hose from the reg to the valve - which is what I have now is perfectly fine.
I am a pro filter guy, because salty water and a crystal of deposited gunk in small holes with high velocity O2 around is not good. I think of them as cheap insurance. The fact that a filter converts a 3/8" female to a 9/16" LP male is an added bonus, I would need to convert it anyway so I might as well use a filter over a blank adapter.

I've got a custom 3 button needle valve from Chris Kennedy on my sidekick. Dil / Oxy / Offboard -> Common gas out. It's nice. No complaints. stuck it in the mud - still works. I'm happy.
They are all just boxes with the same stuff inside - use whatever you want.

My needle valve shows up Monday, so I was diving my normal kiss mav yesterday. The ppO2 still kept creeping up on me at rest. I had to turn down the IP even more; to about 110 psi on my IP gauge. I dont understand why kiss even bothers with a 0.0035" orifice, they should be just supplying these things with 0.0030" in the first place.
OP
The needle valve (from Charlie) is fun, but I sure end up fiddling with it a lot. Once I add a scooter and a bunch of saw-toothing it gets really fiddly. I may end up blocking the first stage after all. I only have so many hands. I'll give the dynamic IP a few more dives to settle into my brain. I do wish the needle was finer, its only ~2/3rds of a turn from high to low.
