These work great, a good addition to our Oxygen hoses, helps keep the twists out

It for perfectly into the O2 line and keeps the line from kinking too much. Priced fairly.

These oxygen machine to hose connectors work great. They swivel just fine ang allow me to get the kinks out of the first section of hose. Understand that they are not real loose. I don't think you really want them to be Too loose but if you have 15 feet of oxygen hose swiveling around and stuff you don't need it to be real loose The torque provided by the hose itself is enough to turn and allow you to straighten the hose. Good job I will definitely buy more if I. need them and recommend them wholeheartedly.

Working great so far. My hose has been yanked off a few times but has never kinked and that is what I bought it for.

I like this it keeps the hose or tube from bending.

Excellent item I so much needed this

These connectors are the best

I used these with an line flow meter that allows me to decrease the oxygen I receive when sitting and increase the oxygen when moving. I have a 10 lpm O2 concentrator and they don't hold the tubing when I turn my O2 down on the inline flow meter which creates more pressure on the connector. I recently had my concentrator exchanged for a comparable concentrator. They worked well on the old concentrator.
