Oxygen, anyone?

What part of preventive maintenance is this? How does an owner document this in the log book?

Do you want to be counting on the oxygen system to be working when it fails because of an O ring not installed correctly?

If you do not have the training and certification to perform this maintenance action, you have absolutely no business working on a life support system. Servicing the bottle is different.
