Rick,
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.

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.
