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.

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.
