20 Pack Oxygen Tube Support Crimp Straighteners for Portable Concentrators, Tanks, Hoses, and Nasal Cannulas – Essential Oxygen Tubing Accessories

awesome product

The oxygen tubing for my mother's portable concentrator always gets crimped right at the end.I tried these straighteners to see if they would help support the tubing and keep it from crimping.As you can see in the pictures, it works! The pictures are of the same cannula, I just applied one of these for the second picture. It keeps the tubing from crimping and in this case, even opened the tubing back up from having been crimped. She has a very long tubing to use with her home concentrator and that tubing gets crimped from time to time. I'll use one of these on the next crimp she gets with that tubing as well.They are a little longer than they need to be for most use cases I can think of, but longer is better than too short. I might try to cut them in half. The colors in the package were half baby blue and half light pink.These are inexpensive and effective so I absolutely recommend them.

It works decently to minimize the cannula twisting. I wish the colors were different because pink and blue are a little amateurish looking for adults. They are easy to use.

These work exactly as advertised!
