||The medical size "D" oxygen cylinder is a great choice for
anyone who needs a very portable oxygen system with a significant oxygen
supply. The MD cylinder holds 415 Liters of Oxygen gas and is great when
partnered with our PHTLS Pack.
This cylinder comes with a choice of valves including standard post,
toggle post or a "Z" valve, a hand tight valve that eliminates
accidental opening of the valve and pressurizing of the system. All
cylinders are shipped empty.
