BUYING WELDING OXYGEN – REFILLING PORTABLE O2 CYLINDERS
Buy compressed welding oxygen at your local welding supply shop or any welding supply in the world, like welders. We use two sizes of commercial non-disposable high pressure aluminum oxygen cylinders (9 lb and 3 lb) with 540 CGA Global valves. A full fill is 2200 PSI, less than 2200 PSI is only a partial fill.
Welding supply shops will refill your small portable OE cylinders for $12-$15 or with our refilling adapter, you refill your cylinder for pennies; you refill your OE portable cylinders at home or any place in the world.
All OE oxygen cylinders must be hydrostatic tested every 5 years, a high pressure cylinder safety issue. The hydro date is stamped into the metal on the cylinder shoulder. The Hydro mark for March 2014 may look like this 03 ∆ 14 or 03 ◊ 14.
Refill your OE cylinder yourself for pennies, not $, in minutes at your convenience at home.
Contact your local welding supply shop to rent a large oxygen 281 cu. ft. cylinder for $4 month or buy the large cylinder. Return empty large cylinders to the shop and exchange for full cylinders.
Buy the oxygen gas contents $7-$13 (large 281 cu ft O2 @ 2200 psi is “full” – OE cylinders are also full @ 2200 psi). Take the large empty cylinder back to the shop and exchange it for a full cylinder when necessary. Some welding shops will deliver the large cylinder to you. This is the most economical method of buying source oxygen that ensures minimal operating cost in the long run.
Your OE regulator will also connect to the large oxygen cylinder 540 CGA valve when you need to keep your bait oxygenated at home overnight or several days. Reconnect the OE regulator to the small OE cylinder when you need mobility the next morning.
BUYING OXYGEN – OE-D SYSTEM DISPOSABLE O2 CYLINDERS
Use for Emergency livewell oxygenation when live bait or tournament fish are in crisis or for small amounts of live bait (a handful of shiners – 3-4 oz of live bait)
The OE-D oxygen system uses BernzOmatix® disposable oxygen cylinders. Buy these oxygen cylinders off-the-shelf at many locations; Ace Hardware, Home Depot, Lowe’s, and most plumbing supply stores. Cylinders are sold as singles ($5-$8) or buy economy 12 packs ($40-$50). If 12 packs are not stocked, most store managers will place a special order for you. BurnzOmatic oxygen cylinders contain 99.9% oxygen @ 500 psi (1.1 cu. ft. gas @ 70 F. Empty cylinders disposal – any dumpster. No wrenches needed to connect the adjustable brass regulator to the BernzO cylinder. Cylinder and regulator connections are left-hand threads. The OE-D regulator will not connect to refillable OE cylinders with CGA 540 valves (right-hand threads).

*Did you know that the only difference between a medical compressed oxygen gas and a commercial welding oxygen gas is the fixed label attached to the cylinder wall and the cost of the gas? The gas purity and humidity (water vapor content) is the same.
Compressed aviation oxygen is required to be dryer (less water vapor content) than medical and commercial welding oxygen, the purity is the same. Aviation oxygen must be dryer (contain less water vapor) because freezing temperatures. Extremely cold temperatures at high altitudes can cause the water vapor in the oxygen to freeze oxygen regulators causing oxygen life support systems to malfunction and fail in flight.
Extreme cold is also issue for high altitude mountain climbers that use supplemental oxygen.
