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

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.

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.
