Sea Dan, Do you have a drawing or data on
Phil's tilt/demand system? Rick Rick, I am building a K-350 and am
trying to get as many thru hull fittings welded in as I can before welding the
end caps on. For anyone who has the plans for a K-350, did you actually follow
drawing 041-2? it is the Phos. bronze removable piece for the 02 to pass threw
and looks quite expensive to machine if not doing it yourself.
I would like to hear from anyone
regardless of boat type that uses an 02 life support system what they welded
in for a threw hull fitting. I can't see why I just can't weld in a schedule
80 ss 316-L pipe coupling then screw into that a HP valve then HP to
LP 02 regulator then a proper flow meter for 02?? I would 02 clean
the nipples and coupler of course. Also any feed back for
the ID of pipe I should use would
be appreciated. Rick

This system works brilliantly. The heart of the demand valve is a
small bellows. Maybe Phil would give us some specifications of it.

I built my K-350
according to the plans and made the Phos. bronze fittings. If I had it to do
over again I would skip that part and bring the O2 into the cabin at low
pressure instead of high. Stainless steel is not favored for HP oxygen
service. Phil Nuytten has the best system going with the tilt / demand
valve.
