One my O2 masks looks to be loosing oxygen as soon as I hook it in I loose oxygen within a day or so on the pilot side. The other one is holding still making sure. Has anyone had any luck with getting the Oxygen Masks overhauled or repaired. I saw that on a website called Aviation Oxygen. Otherwise I would just buy a new one. Is there such a thing as buying a used one. I guess you don't really need them. Or you hope you don't but when you do. It's a must. Any input would be great.
