590 Series Parker Parflex Hose
*Note: Beginning January 1, 2017, the 590 series hose will be discontinued by Parker. The 590TJ Series hose is recommended as a replacement. (For sizes 590-10, use H6 or 594TJ series hose. For 590-3, use the 575X series.) Please note that 590TJ has a tough-jacket cover and a smaller O.D. A new crimp die will also be needed for this hose. 590 hose will still be available on special order, but will have longer lead times.
