BNC-Scott Oxygen Connectors

[Fly Boomer]

I want to order some BNC-Scott oxygen connectors from Mountain High, but their web site asks me to choose from 3 FLOW TYPES:

a) Filter Only, used with flowmeters or a regulated flow device.
b) #8 orifice (.008″) used with fixed flow, no flowmeter, Cannula.
c) #16 orifice (.016″) used on fixed flow, no flowmeter, mask, generally for Emergency.

Note: All options are filtered.

I wish I was smart enough to know what they are talking about.  Can anyone help?

They are good on the phone. You tell them what airplane you have - they'll tell you which ones to get

If you need a flow meter, highly recommend Precise Flights A5. they’ll sell you one with the scott connector.

Do you like the mic mask that comes with that kit?
Now that I think about it, if you are a climber, you probably don't need no stinkin' mask.

The ones with the orifice are for constant flow systems. I would suggest getting flow meters and getting the filter only connectors. That way you can determine how much oxygen you get. Besides, it will probably save you Money. And we own Mooneys, so we are cheap bastards.

yes, the mask with the built in mic is the only way to go into the flight levels. Actually i really do need mask, but my wife , the high altitude mountaineer does fine with just that oxy-miser cannula all the way to 23-24K’! but not me

Call mountain high and have photos of your connectors or ports, which ever you have.  I purchased the pulse demand unit which required an inline regulator to drop the pressure.  The pulse demand cut my O2 use by 75%.

The O2D2 is the only way to go.

I just used it on two 3+ hour flights and cannot see that the O2 system pressure needle moved.
