only has to be cracked less than a quarter turn. My other four gliders
had the bottle where a determined pilot could reach back to the baggage

Mountain High has a clever remote valve operating device for their
cylinders.

Some older oxygen cylinder valves may leak past the stem if not fully
opened. I open O2 valves fully to seat the stem seal.
