Help with the "whip"

[camarillorose180@gmail.co]

I just bought an oxygen concentrator and I am looking for a part called the "whip". A hose that connects the machine to my tank for filling. Can anyone point me in the right direction?

A concentrator won't fill a tank. You need a Homefill machine or similar that works in conjunction with the concentrator to fill a tank.

once you do get the homefill you will have to build the whip.
