Parker 721 HoseThe 721 hose offers flexibility for high-pressure applications. Users can expect to use less hose and to easily install the hose in tight spaces, according to the company. Working pressure ranges from 2,500 to 4,000 psi, depending on inside-diameter size. The hose can handle a variety of petroleum-based hydraulic fluids and lubricating oils, water/oil emulsion and water/glycol hydraulic fluids. Four spiral layers of high-tensile steel wire provide reinforcement, and a black synthetic rubber cover provides oil and weather resistance. A tape layline makes the 721 hose easy to identify.
