OxyCon hose/Y connector question

[WhiskerWood]

I have two oxygen concentrators with a Y connector, the diameter of the hose seems very small to me, the inside diameter is 7mm.
My question is, does the small diameter of the hose hinder my oxygen flow?
Would it be better if I had a larger diameter hose/Y connector?

Probably not....... You have to remember its not much volume or pressue involved here...

Besides 7mm is a tiny bit larger than 1/4 inch and most hoses we use with any torch setup is only 1/4 inch id ...
