You cannot use 100% O2 with standard scuba equipment. O2 in contact with
petroleum based products can cause an explosion or fire. Standard suba makes
extensive use of petroleum washers, screws, etc in the manufacture of the
first and second stages. The demand valve for an O2 kit is made specifically
for O2 delivery.
