These are high quality good looking stickers. If you are certified to properly service and inspect your tanks, this is a must in order to take advantage of your investment in that training.
Please remember to inspect aluminum cylinders crown threads with a small magnified mirror and a bright light or eddy-current deice. Also remove older (pre 1988) 6351 alum alloy cylinders from service if possible. SLC (sustained load cracking) is rare but easy to overlook so take your time when doing the inspections. The life you save may be your own.
