I bought these to replace the hoses on the pressure gauges which I already had but with a split outer jacket on the supply hose (yellow). They are more flexible and feel nicer than the old tubes so I'm sure they will last longer. The ends are also of good quality. I chose them over other hoses available because of the over pressure protection feature which compares well to burst hoses as you can see by the tiny holes in the outer sleeve. to say the least, and I look forward to getting more years out of my gauges.
