Oxygen Cleaning

Any cylinder exposed to oxygen concentrations greater than 40 percent must be O2 clean. This includes:

• Nitrox cylinders filled via partial-pressure blending
• Decompression cylinders
• Aviation and medical O2 bottles

What does O2 cleaning entail?

• The inside of the cylinder must be completely free of any potentially combustible material such as carbon deposits, oil or non-oxygen-compatible lubricants. This requires a special cleaning process.

• The cylinder valve must be completely disassembled and cleaned in an ultrasonic bath until, like the tank itself, it is completely free of potentially combustible contaminants.

• Prior to reassembly, the valve’s O-rings and other components must be replaced with one using oxygen-compatible material such as FKM and Viton.

• The cylinder and valve must be reassembled using oxygen-compatible lubricants.

Turnaround times for oxygen cleaning will vary depending on the condition of your cylinder.

• If a cylinder is in excellent condition, we can complete the process in as little as 24 hours.

• A steel cylinder that requires tumbling to remove rust may take us as much as three days.
