Product review (3 stars): Good Quality But restricted flow
This is a very good quality hose. However, the I.D. (internal dimension) is not as big a step up from a 3/8 hose as I wanted. I was attempting to improve the water flow rate to my new washing machine. But this hose has a venturi on the end of the hose for a stronger end connection. This creates an opening only 3/64" greater than the 3/8" hose that I was replacing.
