### ⭐⭐⭐⭐⭐ Review
*by A***R on 7 November 2025*

These fit my oxygen tanks perfectly and the multi pack is a SUPER GOOD value for the money! I keep one with each tank as well as carry one in the car. I was concerned about the quality, but these are solidly made, no fear of them stripping or cracking like happened to me with one from a different vendor. These also have the hole on the end so you can tie and tether them to the oxygen cylinder. Great value for the money, and very pleased with the quality. Multipack is the way to go. Seems like a really reputable and quality product.
