Don’t
mean to step on Dan’s
toes but I think this is what you are looking for:

Do you have a drawing or data on
Phil's tilt/demand system?

Rick,
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.

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.
