Oxygen
If you are on oxygen these have to be replaced all the time and companies will only give you so many. Now I have enough to have some in the car, home, each oxygen bag(tank) so I don’t have to worry about it.

Always have some in a small ziptop bead bag just in case.
These seem to be better made than the seals sold by home medical stores.

Must have
Everyone on oxygen tanks needs these. I had 3 out of 4 tanks that lost their seals, and my delivery company only comes to my area weekly. I didn't even know why my tanks weren't working until I called them, then when they delivered my next order, they only gave me 2 washers. I am getting a pack now as well as extra tank keys just in case. Be prepared!

Quality cut!
I liked it all. But not looking under the table if I happen to drop one is best.

Perfect
These are not cheap or flimsy. You can have confidence that these will not break easy and you can use your tanks worry free
