YES I was told by a friends supplier to stretch the hose. My husband puts it under his foot and stretches it that way or just pulling it with your hands works but a little harder. It will not twist Soo much nicer!

I have found that using two 25 foot air lines with a swivel connector between helps keep them from kinking if I have to use a 50 foot line I have a lot of trouble with it kinking also the green lines don't kink as bad as the clear ones did.

I used to have the same problem...get 2 25' tubes instead of 50 and use a short one from the accumulator with swivels between all the links. Works like a charm.

i want to create a hose that retracts like the hose on the tv

My oxygen company gives me swivels to connect so you don't get twisted up
